Sheldon Lee Cooper, also known as Sheldon Cooper, Shelly, Shelly Bean, Moonpie, Smelly Pooper, Dr. Dumbass, Dummy, Passive-Agressive East Texas Blowhole, Virgin Piña Colada, C3P-Wee Herman, Sheldor, Shelbot, R2-D-Bag, Einstein von Brainstorm, Professor Cooper, The Skinny Weirdo, Stretch and Skippy Cavanaugh, is one of the main characters from The Big Bang Theory series.
== Charactah Account ==
Leonard's roommate. A child prodigy, he graduated from college at the age of 15 from East Texas and specializes in Theoretical Physics. Supposedly the smartest of the guys, but he only ends up dominating arguments and debates (both in science and in nerd trivia) because he's too stubborn to quit and resorts to crazy logic to win. His dedication to science and geekdom is so complete that he has almost no interest in social skills, regular pop culture (current fads, celebrity gossip, etc.) or even romance. He thinks he's superior to... well, to everyone.
Aside from his characteristic idiosyncrasies, obsessive–compulsive disorder, obsessions, and extreme narcissism, Sheldon does not understand why humans are illogical and tries to be logical himself. (Though he is actually more illogical than most people in so many ways Ex: Fear of change, fear of birds, expecting others to change for him, throwing childish tantrums, being immature, etc.) He possesses an eidetic memory and an IQ of 187, although he claims his IQ cannot be accurately measured by normal tests. Sheldon has an overly extensive general knowledge, such as shown by his comments regarding various details of anecdotal knowledge (for instance, about the introduction of the fork into Thailand). It was also revealed in "The Sales Call Sublimation" that Sheldon, possibly, has synesthesia. He told Raj that he automatically sees prime numbers as red and that twin primes appear pink and smell like gasoline. These are characteristics of people with synesthesia.
Sheldon also has qualities associated with being a prodigy, such as an inflated ego, social ineptitude, and an inability to relate emotionally with other people. Despite his intelligence, he has a distinct lack of emotional maturity and is often baffled by even the most common social interactions. He not only fails to understand the simplest sarcastic jokes made by his friends, but also regards their sadness over problems with blatant confusion.

== Trivia ==
* In the episode The Bachelor Party Corrosion, it is implied that Sheldon has strong feelings about NAFTA, a free trade agreement that came into force in 1994.
* Sheldon will end up being the character with the most appearances in the entire franchise by the time Young Sheldon ends unless another character gets a longer sequel.
* In "The Russian Rocket Reaction", Sheldon reveals he was 9 years old when he started his all-time enemies list on a 1989 floppy disk.
* His age is further constrained by the following consideration: Sheldon is a Taurus, according to "The Peanut Reaction", placing his birth date between April 19 and May 20 of 1980. This age is supported by Leonard's comment that Sheldon has been emotionally stuck for about 29 years in "The Einstein Approximation", with an air date of February 2010; however, a family chart in "The Cruciferous Vegetable Amplification" shows that he is 29 at the time of the episode, which aired in September 2010. Further, in "The Friendship Contraction", premiering in February 2012, Leonard described Sheldon as a "30-year-old man who can't survive on his own". (Though, it is possible Leonard was just being imprecise.) These latter two statements indicate a birth date between April 20 and May 21 of 1981 in the span of the Taurus. [Note that inconsistencies arise only if one assumes a temporal correspondence between the airdate of the referenced episode and the events featured in that episode. Therefore, Sheldon should be considered to have been born between April 19 &; May 20, 1980.]
* In The Celebration Experimentation and in A Rival Prodigy and Sir Isaac Neutron , Sheldon mentions to that he is born on 26th February 1980 making the Taurus theory false.
** In real life, Jim Parsons, being nearly 7 years older, was the same age as the high school students Sheldon went to school with..
* Sheldon is 6 ft 1 in (1.85 m) tall [1] – the height of Jim Parsons. (Parsons claims to measure 6 ft 2 in (1.88 m), presumably with shoes and the Sheldon life-size standup poster is 74 inches in height.)
* He weighs either 165 lbs (75 kg), as revealed in "The Porkchop Indeterminacy", or 140 lbs (63.5 kg), as estimated in "The Luminous Fish Effect"; however, those are most likely inaccurate now, due to the amount of time that's passed.
* He has been described as a "tall, thin... praying mantis" by both Penny and Amy Farrah Fowler.
* According to his mother, Mary Cooper, Sheldon has her eyes, his daddy's temper and "all that science stuff" comes from Jesus.
* Several ways to annoy Sheldon are laid out in "The Bad Fish Paradigm" (S02E01), including:
** Change the brightness/contrast settings of the television.
** Take a Band-aid off in front of him.
** Buy generic ketchup.
** Forget to rinse the sink.
** Talk to him through the bathroom door.
** Adjust the thermostat.
** Cook with cilantro leaves
** Pronounce the 't' in 'often'
** Make fun of Model trains/trains
* Mary's water broke for Sheldon and Missy in a Kmart, not a Walmart.
* Sheldon is rarely interested in sports, but is highly skilled at bowling and can consistently get strikes. ("The Wheaton Recurrence")
* Sheldon was raised in a Christian household in Galveston, East Texas, Texas, USA (Texas just happens to be the same state that Jim Parsons was actually born in), although he once said his mom had to help his dad during tornado season, as the aluminum house he had slipped off its cinder blocks. (This could have been his father's way of a tornado shelter or his parents divorced by then and he moved into an aluminum trailer. The reason for these explanations being as we saw Sheldon's childhood home in the season 3 premiere, where his mother still lives.)
* In the “The Excelsior Acquisition”, Sheldon states his belief that the universe we live in is deterministic but we still have free will.
* Sheldon has perfected "glow-in-the-dark fish"
* Sheldon has 212 friends on MySpace, even though he hasn't met one of them.
* Sheldon is allergic to bees and cats and gets asthma when he is around them (despite having a pet cat as a child and a whole glaring of cats when he missed Amy.)
* Sheldon considers himself to be the first "Homo novus" - a new, evolved species of Homo Sapiens.
** Homo Novus translates from Latin to "The New Man".
* Sheldon doesn't believe in luck or coincidence, instead citing the Law of Large Numbers (LLN) in statistics as the explanation for such phenomena.
* Sheldon hates going to the local Renaissance fair because he doesn't like the historical inaccuracies, such as Bavarian purity laws, mead flagons made of polypropylene, "ye olde" being put in front of everything, even modern underwear.
* Sheldon was humiliated on national radio during NPR's Science Friday with Ira Flatow when his voice became extremely high pitched due to helium seeping into his office as part of a prank by Barry Kripke.
* Sheldon agrees with the theory that 75-80% of any Rock-Paper-Scissors games you play with a person you are familiar with end up in a tie due to the limited number of outcomes and accordingly he prefers the variation Rock-paper-scissors-lizard-Spock/Rock-Paper-Scissors-Lizard-Spock.
* Sheldon used a Doppler Effect costume for Halloween.
* Sheldon uses his Green Lantern action figure as a safe place for his emergency money.
* Sheldon is fluent in Morse code.
* Sheldon believes that chocolate is the best flavor of pudding, trumping tapioca because of its high concentration of cyanide.
* Sheldon's favorite amino acid is Lysine, which is a major plot point to control the dinosaurs in the novel/movie Jurassic Park
* Sheldon thinks that his very strong attention to hygiene and his skill in writing Java Applets are the main reasons why his friends like him.
* Sheldon loves trains and monkeys.
* Sheldon contests that you can put a number to anything, including Rubik's cube stickers as well as friends.
* Sheldon fears dogs, dinosaurs, chickens and formerly birds.
* Sheldon had a cat named Lucky when he was a child, and this cat died because it was hit by a car. According to Leonard, this is another example of Sheldon's inability to understand irony.
** Sheldon thought about creating a griffin after Lucky was killed, but his parents didn't want to secure the appropriate eagle eggs and lion semen.
* Sheldon learned how to swim (on the floor) online. He went into the pool with Ramona Nowitzki in season 10.
** This appears, however, to contradict an episode of Young Sheldon in which he is forced to swim for P.E, though he barely succeeds.
* Sheldon cannot stand whistling. ("The Friendship Algorithm")
* Sheldon was very busy in his teenage years examining the range of diffusion in the super-symmetric theories, which brought him to re-examine the ultraviolet properties of Higher-dimensional supergravity a loop.
* Sheldon's expenses account for 46.9% of his after-tax income.
* According to Leonard, Sheldon doesn't like furniture made of reclaimed wood cause he believes the original owners will come back to take it.
* Sheldon imposes and teaches behavior lessons to any friend of his who disappoints him for three consecutive times.
* Sheldon thrives off his work and if left jobless he loses all focus and moves onto a new experiment/obsession every day, much to Leonard's dismay.
* Sheldon does not like teddy bears because he thinks bears are terrifying. He later told Amy that he does have one and that he often used it to wipe his nose.
* Sheldon was called by Leonard "one lab accident away from becoming a super villain".
* According to Leonard, Sheldon loves having his brain scanned.
* Sheldon only shows genuine affection for one person, his grandmother (or Meemaw), whom he writes too at least for most of the show.
* Sheldon is a Taurus, placing his birthday between April 21 and May 20, however, his birthday is apparently February 26, which makes him a Pisces, causing a continuity error. Though, it's possible that Penny guessed he was a Taurus.
* Sheldon, though unwilling to fight, is physically the strongest of the group, easily holding his own against Raj in an arm wrestle, and once referred to Leonard and Howard as 'tiny tiny men'. He was also able to move his entire dresser, with reasonable ease when barricading his door, due to paranoia, after being burgled.
* Sheldon owns a pocket watch. He bought it for himself when he was shopping for Amy to get her back in "The Shiny Trinket Maneuver". It is seen again in "The Locomotive Manipulation".
* Sheldon's little toes and lateral incisors are degenerated, which he says is due to his high level of evolution which keeps him from using a motor vehicle correctly.
* He says that he thinks that Erno Rubik, is a lonely guy.
* Sheldon once took a bet with Howard about a species of cricket, but lost and had to give Howard his rare Flash comic book.
* Sheldon went to a sci-fi convention on a bus for 10 hours and violated his personal rule of not urinating on buses twice to see Wil Wheaton, who didn't show up at the convention, which was revealed in season 5 that it was because Wheaton thought it be cooler to play on "Hollywood Squares". This and the events of the card tournament and bowling alley, led Sheldon to consider Wheaton his nemesis. He has made three websites dedicated to hating him: Willwheatonstinks.net, org and .com. It is unknown if Sheldon still has these websites after making up with Wil Wheaton.
* Sheldon has actually been kind to Penny; in two episodes he actually drove her to the hospital because she dislocated her shoulder after she slipped and fell in the shower and loaned her a significant amount of cash to help her in a financial pinch. The latter favor led Penny to think everyone was grilling her on her financial situation, even when they weren't.
* Sheldon was once offered a position at a secret military base but was later forced to deny the position due to his inability to keep secrets.
* Sheldon thought that the trip he and his friends took to the North Pole in Season 2/3 was "a hoot and a half."
* It was mentioned that Sheldon and Leonard once had (before they were robbed) "A TV, 2 laptops, 4 external hard drives, a PS2, PS3, Xbox, Xbox 360, a classic Nintendo, a Super Nintendo, a Nintendo 64, a Nintendo Wii, Halo 1-3, Call of Duty 1-3, Rock Band 1-2, Final Fantasy 1-9, Legend of Zelda, Legend of Zelda: Ocarina of Time, Legend of Zelda: Twilight Princess, Super Mario Bros, Super Mario Galaxy, Mario and Sonic at the Winter Olympics and Ms. Pac-Man. They also own Grand Theft Auto and Red Dead Redemption by Rockstar Games. They then probably got all the games and consoles again with a new T.V. and new computers. Sheldon's data was safe as well, as he was performing a backup in the previous episode. His new computer came with Windows 7 which he doesn't like cause it's much more user friendly than Windows Vista.
* Sheldon has adhesive whimsical duck stickers, holding umbrellas in his bathtub to prevent slipping.
* Sheldon keeps a daily log of social interactions called Sheldon's Log (in reference of Captain's Log).
* Sheldon doesn't trust banks because he believes that ATM machines will lead the charge of the robot armies when they revolt against humans.
* Sheldon keeps Band-Aids with him at all times, as well as in his kitchen, top desk drawer etc.
* As of "The Excelsior Acquisition" (S3E16), Sheldon has a restraining order from Stan Lee as well as the late Leonard Nimoy. In "The Vacation Solution" (S5E16), he also mentions having one from the late Carl Sagan. In "The Proton Displacement" (S7E07), he gets a new one from Bill Nye the Science Guy.
** Due to Sagan and Nimoy being deceased, it's possible that these restraining orders are null and void, unless they are also in effect for their final resting places.
* Sheldon doesn't seem to understand the concept of racism. This is implied in "The Egg Salad Equivalency" when he calls Mrs. Davis a slave to her sexual desires, even though she is black. In "The Tenure Turbulence", he also gives her the HBO series Roots, which is about the slave trade in America.
** Though he does sometimes demonstrate a base understanding of the civil rights movement he does not understand, seemingly, its connection to racism.
* Sheldon has an in depth knowledge of American Football, only because he was raised in Texas and his father, a football coach, would force him to watch it from the time he was four until he went off to college — the longest seven years of Sheldon's life.
* Sheldon rarely laughs but when he does, it's a quick internal breath while showing a small smile. One of the rare times we hear him laugh properly is in season 5's "The Vacation Solution" over a physics Mad Lib. Another time, he has laughed like that is when Leonard made a multiplication error that was published.
* Sheldon has never worn a shirt with words, unless a shirt logo has words on it, like in episode 5 of season 4 and near always wears a long sleeved shirt under a t-shirt.
* Sheldon got drunk four times during the series: at the end of "The Grasshopper Experiment", "The Pants Alternative", "The Stag Convergence" and "The Habitation Configuration. In the last two, he showed a sense of humor and irony above what he normally has.
* Sheldon apparently believes in the possibility of time travel to the past according to the beginning of "The Luminous Fish Effect", explanations of time paradoxes in "The Nerdvana Annihilation" and a point of the room-mate agreement in "The Staircase Implementation".
* When somebody is distressed, Sheldon consoles them by saying "There, there", the only proof of his compassion towards other fellow human beings.
* Sheldon doesn't seem to like Internet memes, considering them "venality". He once gave Penny a "strike" (out of three and you're out) for sending him a picture of a cat who wants to "Haz cheezburger". He also put Leonard's e-mails in his spam folder over Leonard sending him a video of The Keyboard Cat.
* Sheldon is scared of waking Penny before 11 A.M., because she has an "I'll punch you in the throat" rule if he does.
* Sheldon is skilled in weaving as he is seen weaving ponchos in his apartment.
* If nothing is approved by Sheldon, he will not go through with it. (This is seen when Leonard, Raj, Howard, and Sheldon are trying to figure out the best way to see a movie. With Sheldon not approving any ideas, the others leave him. He responds: "They're right. It was the only option.")
* "Prevening" - Sheldon's made up word for the hours too late for afternoon, but too early for evening.
* Leonard had to surpass three barriers set by Sheldon in order to live with him in "The Staircase Implementation".
* Sheldon prefers the word "Hokum" over Bogus, Hocus Pocus, Mumbo Jumbo and Hokie Pokie.
* He considered Amy Farrah Fowler a friend, who is a girl, but not his girlfriend. This statement, however, is moot since "The Flaming Spittoon Acquisition" when the two officially become a couple.
* He missed getting Stan Lee to autograph his comic since he had to go to traffic court to pay a fine, but ended up in jail after he insulted the judge and refused to apologize. He then went to his house with Penny and ended up with a restraining order against him.
* Sheldon had built a robot called Shelbot, but was eventually discarded since Penny and Leonard were quite annoyed at Sheldon's idea for doing so.
* Sheldon owns a Flash costume which he has worn on three occasions: in "The Middle-Earth Paradigm" before Penny's Halloween party before switching to a Doppler Effect patterned suit, in "The Work Song Nanocluster" when high on caffeine and in "The Justice League Recombination" when attending a New Year's Eve costume party.
* Prior to Sheldon's date with Amy in "The Robotic Manipulation", the closest he had ever come to one was "a semi-incestuous Teens for Jesus Fourth of July Hoedown" at which he square-danced with his twin sister, Missy.
* Sheldon once attempted to declare his and Leonard's apartment a sovereign state and even made some currency for it. This was around the time Sheldon got fired from the university and he kept changing obsessions.
* Sheldon hates dirty socks. This is demonstrated by the time that Leonard, Raj, and Howard signed Sheldon up on a dating site and the site found Sheldon's perfect match, but Sheldon refused to go until Raj told him that he put a dirty sock in his apartment and would not remove it unless Sheldon went on the date.
* According to Sheldon in a deleted scene/blooper in "The Maternal Capacitance" the last time his mother visited, she tried to trick him into getting re-baptized below the Santa Monica Pier.
* Sheldon went to Johnson Elementary School until he went to college at age 11. It was there he earned the nickname, "Smelly Pooper" with kids going around saying, "Shelly Cooper is a Smelly Pooper". Amy believes this is gold for gossip.
* When Sheldon was under the influence of Howard's mom's Valium, he revealed that his mother used to smoke in the car. While "Jesus said it was OK", they couldn't tell their dad, George.
* Due to his good archery skills (taught to him by his father, George), Sheldon believes he would have made a great elf.
* There are two pieces of tape on the floor in Leonard and Sheldon's bathroom. One is in front of the sink and people must brush and floss their teeth from behind this piece of tape. A second piece is in front of the toilet "for those that stand up to pee", though what exactly it marks was not specified. If someone gets the mirror or floor dirty, before Sheldon's inspection, they can lose their T.V. privileges.
* As part of the roommate agreement created by Sheldon, Leonard has to wash his feet in a special tub before he gets in the tub or shower.
* The tentative title for his future autobiography is You're Welcome, Mankind.
* He had a Somalian pen pal who was kidnapped by pirates.
* Sheldon has to be knocked out by an anesthetic when he goes for a cleaning at the dentist, as he bites.
* In 1998, Sheldon bought a Tamagotchi, which is still "alive" as he puts it.
* Both Howard and Sheldon first connect with their girlfriends over the personalities of their mothers.
* In kindergarten, Sheldon recited Pi to a thousand places for the school talent show.
* In "The Bakersfield Expedition", Sheldon dressed as the Star Trek: The Next Generation character, Lt. Data.
* He might have aquaphobia (fear of water) per the episode "The Friendship Algorithm".
* Sheldon sometimes reverts to his Texan upbringing and uses expressions and ideas from his mother and father that are not as acceptable in the 21st century. (Women are like an egg salad sandwich...), (Swatting Amy on the behind and calling her a great gal.)
* As a child, Sheldon was not allowed to do his homework until after he watched football with his father.
* Sheldon can speak the Hawaiian language.
** Additionally Sheldon also knows Hindi.
* It's implied that Sheldon admires Madame Curie, as he put her in the collage for his screensaver along with Stephen Hawking and Amy.
* Sheldon meets James Earl Jones who likes Sheldon and he takes him out on a night on the town instead of having a restraining order issued against him as Leonard Nimoy, Carl Sagan, Stan Lee, and Bill Nye have done.
* In 2012, scientists at CERN actually DID find a new particle, and after additional research, confirmed that, in fact, the Higgs boson has been found such as Sheldon had been working on.
* Sheldon's abstinence from alcohol may have been an afterthought by the writers early on. In the pilot episode, when Leonard introduces Penny to the gang, he is seen drinking a beverage in a brown bottle with his dinner, which is presumably a beer.
* Another bad habit of Sheldon's is that he reveals himself bad events that he could have gotten away with, such as cleaning Penny's apartment at night, which Penny figured out that it was Sheldon by leaving a list for her closet, and a video message for Kripke after pranking him and inadvertently the University president and board of directors, something he could have easily gotten away with.
* Liev Schreiber - Prototype Sheldon? = He plays a scientist which has few people skills and is working on a weather model that leads him to find holes in time. Physics, time travel, alternate realities, all things that Sheldon is interested in. He looks like he could be Sheldon's brother and often had that squinty eye look while trying to figure out something or when his friends confused him. From the movie "Kate and Leopold".
** The life-model for Sheldon may have been found in the person of physics wunderkind Taylor Wilson, whose life and achievements are remarkably similar, right down to coming from much the same region of the US to the little matter of illegally stored yellowcake uranium used to fuel the working nuclear reactor in the garage - which Taylor built at age fourteen...
* Sheldon's sexuality remains largely a mystery for the first three seasons. It was presumed by most that Sheldon was asexual, which is a lack of sexual attraction to anyone. This is shown when Penny asks what Sheldon's "deal" is, (girls, guys, sock puppets?) In which Leonard responds that they have been operating under the assumption he has no "deal." When Penny insists everyone has a deal, Howard responds "not Sheldon." However, as his relationship with Amy Farrah Fowler develops it appears that Sheldon is perhaps demisexual, which is a largely unrecognized and rare sexual orientation, which is characterized by a lack of sexual attraction towards any person unless they become deeply emotionally or romantically connected with a specific person (Amy). Sheldon appears to feel at least a small amount of sexual attraction towards Amy (most notably in "The Locomotive Manipulation", season 7, episode 15)
* Sheldon is very fond of cats, having owned one as a child and having adopted several when his relationship with Amy temporarily ended. Although Sheldon has issues touching most people, places, things, and animals Sheldon appears to have no issues with touching cats, despite being allergic to them.
* Sheldon's IQ of 187 points places him in a very small fraction of a percent of the most intelligent people in the world. An IQ score is a normalized, scaled representation of the percentage of people that are at least as "intelligent" (as measured by the test) as the scored person. Current IQ tests are scaled to 15 points per one standard deviation (all IQ tests have 100 assigned to the population mean score), older tests (e.g. the popular Stanford-Binet Test) have 16 points per st. deviation. Assuming Sheldon's score is on a modern test, an IQ of 187 means a person with such an intelligence level occurs approximately once per 300 million individuals, i.e. Sheldon is in the top 25 smartest individuals on the planet (using 7.25 billion as the human population of the Earth). If his score were on a SD-16 test instead, he'd have a 1 in 37 million intelligence, and there would therefore be some 200 individuals as smart as or smarter than him in the world.
** However, it’s true that all IQ tests are highly imprecise for extreme values such as Sheldon's (owing to the very small number of people who can achieve such a result, rather than because of bad test design).
** An SD-15 test would assign an IQ of 195 to the smartest individual (i.e., the one with the best result) on the planet (and 194 to the next smartest); an SD-16 test would assign 201 or 202 to the smartest individual.
* Leonard and Sheldon are similar from The Odd Couple. Sheldon is similar to Felix: both are neat freaks and never let things go; difference is that Sheldon is incredibly arrogant and selfish sometimes than Felix.
* Sheldon has an engagement ring that he keeps in his drawer. This ring is revealed to be a maternal family heirloom that was temporarily lost when his Nana had her finger cut off by Comanches. After it was reclaimed, the ring was passed down from generation to generation, until Sheldon received it from his mother.
* Fun fact: there is a Cooper City in Texas, near Dallas/Fort Worth.
* In "The Pancake Batter Anomaly" (S1E11), Sheldon said at the age of 15, he got sick in Germany, and his mother had to fly back to Texas to help his dad at that time. This creates a continuity error in the episodes "The Thanksgiving Decoupling" (S7E9) and "The Proton Transmogrification" (S7E22) because Sheldon mentions to Bernadette's father Mike and to the ghost of Professor Proton, respectively, that his father died when he was 14.
* Sheldon, Leonard, Howard and Raj are the only characters of the current main cast who have appeared in every episode. Howard and Raj didn't appear in the "Unaired Pilot".
* Sheldon always has a habit of putting himself into Leonard's romances, either because he believes Leonard will do something to screw it up, he isn't very considerate of their [Leonard and the woman's] thoughts on it, or he simply does it for no good reason at all other than force of habit.
* Like Penny, Sheldon has/had commitment issues, but in his case, it's not/wasn't as severe, given that he took Amy's hand ("The Countdown Reflection"), initiated his first make out session with her ("The Locomotive Manipulation"), said "I Love You" before she could say it to him ("The Prom Equivalency"), planned on proposing to her ("The Commitment Determination"), and voluntarily decided on having coitus with her ("The Opening Night Excitation"). These examples also prove that despite Amy being ahead in the relationship, Sheldon is the one who takes all the major steps.
* The origin of his knock started after he found his father in bed with a strange woman. Afterwards, he always knocked three times to give people enough time to get their pants on.
* Sheldon Cooper born and raised in Texas and he doesn't have a Texas accent. He sounds more like Frasier Crane and sounds more like a Connecticut country club snob.
** Considering Sheldon's personality, it could be entirely possible that he did have one as a young child, then studied elocution to rid himself of it when he realized that it was, as southern comedian Jeff Foxworthy has joked, "not the world's most sophisticated accent."
* Sheldon has a lot of paychecks that he never deposited in a bank or even used in "The Excelsior Acquisition". Never explained why he didn't use his paychecks to pay his bills, his taxes and his insurance and mostly the rent. How did he stay in that apartment he didn't pay or have any utilities without his using his paychecks to deposit? Only one answer is Leonard, Leonard is the only one supporting him.
* Sheldon and Amy had sex once a year til they got married.
* Sheldon got his driver's license years prior to telling anyone but never drove cause he likes to be chauffeured around, believing it makes him feel important. Actually Sheldon got his driver's license in season 2, but never drove. The streets will be safer if he doesn't. Amy respects his wishes that she chauffeured around.
* Sheldon's right-handed and has the most screen time, surpassing even Leonard in the big bang theory.
* Sheldon skipped kindergarten though grade 1 might be the minimum required start.
* Sheldon loves trains.
* Sheldon's favorite type of cake is a 3 layered chocolate cake with strawberry frosting, as revealed in the episode "The Celebration Experimentation".
* His father used to give him archery lessons, by force though.
* He emails Penny his bathroom schedule once a week, even though Penny has clicked unsubscribe "like a thousand times", he still continues to do so.
* He considers Stuart to be his 9th favorite person, late in the show he's nicer to Howard than Stuart.
* He has a fear of nets.
* He used to have a fear of mailmen.
* He and his mother have an agreement that Sheldon would go to church at least once a year.
* He enjoys reading and collecting comic books.
* Comments over the series indicate that Sheldon's mother is Baptist, and possibly Evangelical, however Sheldon does not believe in or celebrate religion of any kind though.
** Sheldon's mother looks down on Catholicism shown in multiple episodes throughout the series, in one Big Bang Theory episode she visits a catholic church and makes a derogatory comment and in Young Sheldon when Tam says he’s Catholic she says "Well that's too bad,".
* Sheldon's favorite Star Trek character is Spock.
* He doesn't drink coffee because before he left California he promised his mother that he would never do drugs, including coffee, however coffee isn't a drug.
* He drinks hot chocolate but only in months with an R in them, meaning he only drinks hot chocolate in January, February, March, April, September, October, November and December.
* His beverage of choice is moot.
* Sheldon has an Eidetic memory, which can sometimes "be a curse" as he was able to remember the lyrics to the song "We will rock you".
* Raj once used the little rubber part of Sheldon's tooth brush to pick food from his teeth and massage his gums.
* He has to shave every 11 days.
* His favorite character in "The Simpsons" is Lisa Simpson.
* He has never touched Stuart.
* His testicles descended when he was 15.
* He has claustrophobia, a fear of small spaces.
* If his career in physics hadn't worked out, his original plan was to become either a professional ticket taker or a hobo, due to his love of trains.
* When Sheldon discovered that trains could prove Newton's first law, he felt like Neil Armstrong on the moon alone and happy.
* His favorite number is 73, he also has a purple shirt and a blue shirt, both with the number 73 on it in a white circle.
* Sheldon is a big fan of the Flash, as he has many Flash comics in his room, he has many Flash shirts, which he often wears, and he has a safety deposit box which he keeps comic books in some of the Flash, and was upset when he lost a bet to Howard and had to give one of his Flash comics to him.
* He owns nine pairs of pants and nine pairs of underwear.
* He doesn't take the bus when he is sick because he believes that when he pass out, he will wake up with his organs missing.
* He doesn't think that Geology is a real science, as he considers it to be "The Kardashian's of science."
* He wants 15 kids with Amy.
* His favorite color is blue.
* His favorite flavor of ice cream is vanilla.
* Sheldon has been shown to have a disliking towards swearing, however he sometimes swears.
* He and Amy have the same blood type.
* Sheldon can do the splits though he may have lost this ability since he was 9 years old when he displayed this talent.
* Sheldon has synesthesia as revealed in "The Sales Call Sublimation", when he indicates that to him, numbers and tastes can smell and look certain colors or things, such as the color pink and the smell of gasoline for twin prime numbers.
* Sheldon Cooper has a fear of living alone.
* Sheldon and Amy finally won the Nobel Prize in the finale, just hope it doesn't go to his head in the future.
* Sheldon finally thanked his friends and his family for helping him win the prize and helped him become a better person.
