The Gang runs the dilapidated Paddy 's Pub, an Irish bar in South Philadelphia. Each member of the gang shows varying degrees of dishonesty, egotism, selfishness, greed, pettiness, ignorance, laziness, and unethical behavior ; they are often engaged in controversial activities. Episodes usually find them hatching elaborate schemes and often conspiring against one another and others for personal gain, vengeance, or simply the entertainment of watching another 's downfall. They habitually inflict mental, emotional, and physical pain on each other and anyone who crosses their path. They also regularly use blackmail to manipulate one another and others outside of the group. The Gang 's unity is never solid, and any of them would quickly dump any of the others for quick profit or personal gain, regardless of the consequences. Everything they do results in contention among themselves, and much of the show 's dialogue involves the characters arguing or yelling at one another. Despite their lack of success or achievements, they maintain high opinions of themselves and display an obsessive interest in their own reputations and public images. The Gang has no sense of shame when attempting to get what they want and often engage in activities that others would find humiliating, disgusting, or shocking. Some of these situations include pretending to be mentally challenged in order to qualify for welfare, attempted cannibalism, kidnapping, blackface, hiding naked inside a couch in order to eavesdrop on people, tricking a man into giving his daughter a lap dance, forcing each other to eat inedible items, huffing paint, foraging in the sewers for valuables, sleeping with each other 's romantic interests, seducing a priest, secretly feeding someone their dead pet, plugging their open wounds with trash, setting a room full of people on fire and locking the door to avoid an uncomfortable Thanksgiving meal, pretending to have AIDS in order to get priority access to amusement park rides, taking out life insurance on a suicidal person, orally siphoning gasoline, and stalking their crushes. During the Season 7 episode `` The Gang Gets Trapped '', in which The Gang breaks into a family 's home and has to hide from them when they return, an angry monologue by Dennis captures the essence of The Gang 's modus operandi : `` We immediately escalate everything to a ten... somebody comes in with some preposterous plan or idea, then all of a sudden everyone 's on the gas, nobody 's on the brakes, nobody 's thinking, everyone 's just talking over each other with one idiotic idea after another ! Until, finally, we find ourselves in a situation where we 've broken into somebody 's house -- and the homeowner is home ! '' Cast and characters Main article : List of It 's Always Sunny in Philadelphia characters McElhenney, Howerton, Day, Olson, and DeVito at the 2013 San Diego Comic - Con. Charlie Day as Charlie Kelly -- Charlie was a co-owner at Paddy 's Pub, but traded his capital investment for `` goods and services '', half a sandwich, and other undisclosed compensation. He is a childhood friend of Mac, and high school friend of Dennis and Dee. He is also the roommate of Frank, who may be his biological father. Charlie does most of the actual work and maintenance ( referred to as `` Charlie Work '' ) at the pub. He is unable to properly read or write, and is an alcoholic substance abuser who is often seen huffing glue or paint. He lives in squalor with Frank in a run - down, vermin - infested apartment and suffers from deep - seated psychological problems, believing his dreams to be haunted by a figure known as `` The Nightman '', who breaks into his home and rapes him. Charlie has unresolved anger issues, often screaming as a means of getting his point across. He also has an unhealthy obsession with `` The Waitress '', a recurring character who finds Charlie repulsive and shows no interest in him. Despite his character flaws, he is typically the most compassionate and moral member of the gang. Glenn Howerton as Dennis Reynolds -- Dennis is a co-owner of Paddy 's Pub and is Dee 's twin brother. Easily the most sociopathic of the characters, Dennis is abrasive, narcissistic, selfish, histrionic, and vain. Dennis graduated from the University of Pennsylvania. It is at times hinted that Dennis may be a psychopathic serial killer, but this remains ambiguous. After the season 12 finale it is unclear whether or not Dennis will be returning for the show 's 13th and 14th seasons. Rob McElhenney as Ronald `` Mac '' McDonald -- Mac is a co-owner of Paddy 's Pub. He is Charlie Kelly 's childhood friend and Dennis 's high school friend and later roommate. The son of a convicted felon who has been in prison for much of Mac 's life, he frequently attempts to demonstrate his toughness and refers to himself as the `` sheriff of Paddy 's ''. He also often brags about his hand - to - hand combat skills, although he typically flees from physical confrontation. Mac is a Roman Catholic and often espouses strong Christian fundamentalist opinions, despite his often amoral behavior, such as engaging in casual sex with numerous women, including Dee and Dennis ' mother, and a trans woman. Though it is frequently insinuated Mac harbors homosexual feelings, he maintained an adamant denial of any such proclivity, much to the annoyance of the gang. In the season 12 episode `` Hero or Hate Crime ? '', Mac finally comes out. Kaitlin Olson as Deandra `` Sweet Dee '' Reynolds -- Dee is Dennis 's twin sister and is the bartender at Paddy 's Pub. Dee dreams of becoming an actress, although she lacks any apparent talent and suffers from debilitating stage fright. She wore a back brace in high school, leaving her with the nickname of `` The Aluminum Monster '', and she is constantly referred to by the gang as a bird, due to their perception of her as a giant, awkward, avian - like creature. She majored in psychology at the University of Pennsylvania, but did not graduate. Dee lives alone in an apartment. Her comments and ideas are usually disregarded by the others, though they will often repeat what she has said word - for - word and pretend it was their idea, at which point it will be hailed as a great idea. She is often left to deal with the negative consequences of the gang 's activities. Though often the butt of the gang 's jokes, she is frequently involved in their schemes. She is portrayed as the angriest and most physically violent of the group and has a history of assault, including setting her roommate on fire in college. Danny DeVito as Frank Reynolds -- Frank is the legal father of twins Dennis and Dee, and may be the biological father of his roommate Charlie. He used to be a successful businessman with a long history of illegal operations and dealings with sordid characters, but chose to abandon that life and redeem himself after leaving his `` whore wife ''. He has since embraced his `` feral '' nature and describes himself as `` fringe class ''. Despite having substantial financial resources, he chooses to share a decrepit studio apartment with Charlie, where they live in squalor and sleep together on a pullout couch. The two also share similar interests, such as playing the inexplicable game of ' Night Crawlers ' and foraging naked in sewers for valuables. He is also a severe compulsive gambler, seen betting on everything from grade school basketball to Russian roulette, usually with his chain smoking, and high - stakes betting ring of Vietnamese friends. He styles himself a master manipulator and frequently takes the lead in the group 's schemes. He is frequently armed with a handgun and often snorts cocaine as part of his daily routine.

This was then developed into a pilot called It 's Always Sunny on TV and was shot on a digital camcorder by Charlie Day, Glenn Howerton, and Rob McElhenney. It is believed the pilot was shot with a budget of just $200, but Day would later comment, `` We shot it for nothing... I do n't know where this $200 came from... We were a bunch of kids with cameras running around shooting each other and ( the ) next thing you know, we 're eleven years in and we 're still doing the show. '' This pilot was shopped by the actors around various studios, their pitch being simply showing the DVD of the pilot to executives. After viewing the pilot, FX Network ordered the first season. Although it is often stated publicly that It 's Always Sunny in Philadelphia was one of the first shows to be shot in 24p standard - definition video, using Panasonic 's DVX100 MiniDV prosumer video camera, from the sixth season forward, the show was shot in 24p using high - definition video cameras. Danny DeVito joined the cast in the first episode of the second season, playing the father of Dennis ( played by Glenn Howerton ) and Dee ( played by Kaitlin Olson ). In March 2017, after the conclusion of the twelfth season, Glenn Howerton revealed he might not return to the series, due to working on other projects. In an August 2017 interview, Charlie Day said that he believes Howerton will be back, and that he would not feel right continuing without him. Broadcast and syndication The first season ran for seven episodes with the finale airing September 13, 2005. According to McElhenney, word of mouth on the show was good enough for FX to renew it for a second season, which ran from June 29 to August 17, 2006. Reruns of edited first - season episodes began airing on FX 's parent network, Fox, in June 2006, for a planned three - episode run -- `` The Gang Finds a Dead Guy '', `` Gun Fever '' ( which was renamed as `` Gun Control '' ) and `` Charlie Gets Molested '' were shown. The show would not be shown on broadcast television again until 2011, when FX began offering the show for syndication. The third season ran from September 13, 2007 to November 15, 2007. On March 5, 2008, FX renewed It 's Always Sunny in Philadelphia for a fourth season. On July 15, 2008, it was reported that FX had ordered 39 additional episodes of the series, consisting of the fifth and sixth seasons. All five main cast members were secured for the entire scheduled run. The fifth season ran from September 17, 2009 to December 10, 2009. On May 31, 2010, Comedy Central began airing reruns of It 's Always Sunny in Philadelphia. WGN America also began broadcasting the show as part of its fall 2011 schedule. The sixth season ran from September 16, 2010 until December 9, 2010, running twelve episodes, plus the Christmas special. The seventh season ran from September 15, 2011 until December 15, 2011, running 13 episodes. On August 6, 2011, FX announced it had picked up the show for an additional two seasons ( the show 's eighth and ninth ) running through 2013. On March 28, 2013, FX renewed the show for a tenth season, along with the announcement that the series would move to its new sister network, FXX. In April 2017, it was announced by Kaitlin Olson that It 's Always Sunny in Philadelphia would go on an extended hiatus. In an interview with TV Guide Olson stated, `` We ended up pushing our next season a year because we were all busy with separate projects this year. So at the end of this coming shooting season of The Mick I 'll step right into Sunny after that. '' The show is currently under contract for two more seasons and is expected to return in 2019. Music The theme song is a piece of production music called `` Temptation Sensation '' by German composer Heinz Kiessling. Additionally, Kiessling 's work ( `` On Your Bike '' and `` Blue Blood '' ) can also be heard during various scene transitions throughout the show, along with other composers and pieces such as Werner Tautz ( `` Off Broadway '' ), Joe Brook ( `` Moonbeam Kiss '' ) and Karl Grell ( `` Honey Bunch '' ). Many of the tracks heard in the series have been taken from Cafe Romantique, an album of easy listening production music collected by Extreme Music, the production music library unit of Sony / ATV Music Publishing. Independent record label Fervor Records has also contributed music to the show. Songs from The Jack Gray Orchestra 's album, Easy Listening Symph - O - Nette ( `` Take A Letter Miss Jones '', `` Golly Gee Whiz '', and `` Not a Care in the World '' ) and the John Costello III release Giants of Jazz ( `` Birdcage '', `` Cotton Club '' and `` Quintessential '' ) are heard in several episodes. The soundtrack, featuring most of the music heard on the show, was released in 2010.

Emily Nussbaum of The New Yorker praised the show, calling it `` not merely the best sitcom on television but one of the most arresting and ambitious current TV series, period ''. Gillian Flynn of Entertainment Weekly reviewed the first season negatively, commenting `` it is smug enough to think it 's breaking ground, but not smart enough to know it is n't ''. Brian Lowry of Variety gave the first season a positive review, saying it was `` invariably clever and occasionally a laugh - out - loud riot, all while lampooning taboo topics ''. Later seasons of the show have received favorable ratings on review aggregator Metacritic, receiving 70 / 100, 78 / 100 and 85 / 100 for seasons 4, 5 and 6 respectively. The show has become a cult hit with viewers and is often compared in style to Seinfeld -- particularly due to the self - centered nature of its main characters. The Philadelphia Inquirer reviewer Jonathan Storm wrote `` It 's like Seinfeld on crack, '' a quote that became widely used to describe the series, to the point that FX attached the tagline, `` It 's Seinfeld on crack. '' In 2014, Entertainment Weekly listed the show at # 7 in the `` 26 Best Cult TV Shows Ever '', with the comment that `` it 's a great underdog story... If it sounds too dark for you, consider that there 's an episode about making mittens for kittens, and it 's adorable. '' In 2016, a New York Times study of the 50 TV shows with the most Facebook Likes found that Sunny was `` more popular in college towns ( and most popular in Philadelphia ) ''. In 2015, Rolling Stone rated the top 20 greatest and funniest It 's Always Sunny in Philadelphia episodes, stating `` for 10 seasons, the series had mined comic gold from the execrable behavior of the owners of Paddy 's Pub. '' They claimed the two - part season 4 episode, `` Mac and Charlie Die '' is the sitcom 's greatest episode yet.

There are some added moments, added scenes, added songs, and extended versions of songs that already existed. '' Two new songs were included in the performance and a longer running time allowed for greater improvisation by the actors. The performance was also preceded by a preview screening of a season five episode. The Los Angeles performance, filmed at The Troubadour, was included as a bonus feature on the season four DVD box set.
