user: Problem: Background: Hartman was born Philip Edward Hartmann (later dropping one "n") on September 24, 1948, in Brantford, Ontario, Canada. He was the fourth of eight children of Doris Marguerite (Wardell) and Rupert Loebig Hartmann, a salesman specializing in building materials. His parents were Catholic and raised their children in that faith. As a child Hartman found affection hard to earn and stated: "I suppose I didn't get what I wanted out of my family life, so I started seeking love and attention elsewhere."
Context: Working alone as a graphic artist, Hartman frequently amused himself with "flights of voice fantasies". Citing the need for a more social outlet for his talents, Hartman, aged 27, began in 1975 to attend evening comedy classes run by the California-based improvisational comedy group The Groundlings. While watching one of the troupe's performances, Hartman impulsively decided to climb on stage and join the cast. After several years of training, paying his way by re-designing the group's logo and merchandise, Hartman formally joined the cast of The Groundlings; by 1979 he had become one of the show's stars.  Hartman met comedian Paul Reubens and the two became friends, often collaborating on writing and comedic material. Together they created the character Pee-wee Herman and developed The Pee-wee Herman Show, a stage performance which also aired on HBO in 1981. Hartman played Captain Carl on The Pee-wee Herman Show and returned in the role for the children's show Pee-wee's Playhouse. Reubens and Hartman made cameos in the 1980 film Cheech & Chong's Next Movie. Hartman co-wrote the script of the 1985 feature film Pee-wee's Big Adventure and had a cameo role as a reporter in the film. Although he had considered quitting acting at the age of 36 due to limited opportunities, the success of Pee-wee's Big Adventure brought new possibilities and changed his mind. After a creative falling-out with Reubens, Hartman left the Pee-Wee Herman project to pursue other roles.  In addition to his work with Reubens, Hartman recorded a number of voice-over roles. These included appearances on The Smurfs, Challenge of the GoBots, The 13 Ghosts of Scooby-Doo, and voicing characters Henry Mitchell and George Wilson on Dennis the Menace. Additionally Hartman developed a strong persona providing voice-overs for advertisements.

Problem: Background: Oscar Gutierrez (born December 11, 1974), better known by his ring name Rey Mysterio Jr. or simply Rey Mysterio (Spanish for "King Mystery"), is an American professional wrestler who is currently wrestling on the independent circuit. Mysterio is best known for his appearances with Extreme Championship Wrestling, World Championship Wrestling and WWE between 1995 and 2015, becoming a three-time world champion in the latter. Widely regarded as the greatest cruiserweight wrestler of all time,, Mysterio is known for his high-flying Lucha libre wrestling style, which is credited with having helped kick-start the emergence of cruiserweight wrestling in the United States in the mid-1990s. Championships held by Mysterio over the course of his career include WWE's World Heavyweight Championship, the WWE Championship, WCW/WWE Cruiserweight Championship, WCW World Tag Team Championship, WCW Cruiserweight Tag Team Championship, WWC World Junior Heavyweight Championship, WWE Tag Team Championship, and WWE Intercontinental Championship.
Context: Mysterio made his World Championship Wrestling (WCW) debut on June 16, 1996, at The Great American Bash, challenging Dean Malenko for the WCW Cruiserweight Championship, which Malenko retained by winning. In July at Bash at the Beach, he defeated longtime rival Psicosis in a number one contender's match to earn another opportunity at the Cruiserweight title. The next night, on the July 8 episode of WCW Monday Nitro, he defeated Malenko to win his first Cruiserweight Championship. He reigned as champion for three months, which included title defenses against the likes of Ultimate Dragon, Malenko, and Super Calo before he lost the title to Malenko at Halloween Havoc. Following his Cruiserweight Championship reign, Mysterio challenged Ultimate Dragon for the J-Crown Championship, but was unsuccessful in his title match at World War 3 in November.  In early 1997, he feuded with Prince Iaukea over the WCW World Television Championship. Mysterio was defeated in his title match against Iaukea at SuperBrawl VII after Lord Steven Regal attacked him. Mysterio also lost a championship rematch at Uncensored in March. Mysterio soon began a feud with the New World Order (nWo), which culminated when he lost a Mexican Death match to nWo member Konnan at Road Wild in August. Mysterio then became involved in a feud with his real-life friend and Cruiserweight Champion Eddie Guerrero. He defeated Guerrero in a Title vs. Mask match at Halloween Havoc to win the Cruiserweight Championship for the second time. On the November 10, 1997, episode of Nitro, he lost the title back to Guerrero. They had a rematch at World War 3, which Mysterio also lost.  On the January 15, 1998, episode of WCW Thunder, Mysterio defeated Juventud to win his third Cruiserweight Championship, but lost it nine days later to Chris Jericho at Souled Out. After the match, Jericho continued the beating by using a toolbox he found at ringside. This storyline was used to cover Mysterio's need for a knee operation that kept him out of the ring for six months. He made his return at Bash at the Beach, where he defeated Jericho for his fourth Cruiserweight championship. The next night, however, the result was overturned and the belt returned to Jericho due to Dean Malenko interfering. Later that year, Eddie Guerrero formed a Mexican stable known as the Latino World Order (LWO) (a spin off of New World Order) that included nearly every luchador in the promotion. Mysterio continually refused to join and feuded with Guerrero and the LWO members, including winning a match against longtime rival and LWO member Psicosis in a match at Road Wild. He was finally forced to join the group after losing a match to Eddie Guerrero. Mysterio's on-and-off tag team partner Billy Kidman joined him during the feud with LWO, wrestling against the LWO despite Mysterio being a part of the group. His alliance with Kidman was formed after Mysterio helped Kidman defeat Juventud for the Cruiserweight Championship at World War 3. Mysterio went up against Kidman for the title at Starrcade but was unsuccessful winning back the title in a triangle match that also involved Juventud. Kidman once again defeated Mysterio for the title at Souled Out in a fatal four-way match that also included Psicosis and Juventud.
