input: 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.

Question: "Stark Raving Dad" is the first episode in the third season of the American animated television series The Simpsons. It first aired on the Fox network in the United States on September 19, 1991. In the episode, main character Homer Simpson is mistaken for a "free-thinking anarchist" and sent to a mental institution, where he shares a room with a large white man named Leon Kompowsky who pretends to be American pop star Michael Jackson. Meanwhile, because he normally forgets her birthday, Bart promises his sister Lisa that he will get her the best present ever.

The January 30, 1992 rerun of the episode featured a brief alternate opening, which was written in response to a comment made by the then President of the United States, George Bush, three days earlier. The show had previously had a "feud" with the President's wife Barbara Bush when, in the October 1, 1990 edition of People, she called The Simpsons "the dumbest thing [she] had ever seen". The writers decided to respond by privately sending a polite letter to Bush in which they posed as Marge Simpson. Bush immediately sent a reply in which she apologized. Later, on January 27, 1992, George Bush made a speech during his re-election campaign which included the statement "we are going to keep on trying to strengthen the American family, to make American families a lot more like the Waltons and a lot less like the Simpsons."  The writers decided that they wanted to respond quickly like Barbara Bush had to them. However, each episode of The Simpsons takes more than six months to produce, so it is difficult for the show to comment on current events. The writers therefore decided to add a brief response to the next broadcast of The Simpsons, which was a rerun of "Stark Raving Dad" on January 30. Nancy Cartwright, the voice of Bart, was quickly called in so she could record a line.  The broadcast included a new tongue-in-cheek opening. The scene begins in the Simpsons' living room where the family is watching Bush's speech. When Bush says "to make American families a lot more like the Waltons and a lot less like the Simpsons", Bart replies, "Hey, we're just like the Waltons. We're praying for an end to the Depression, too." The opening is featured on the season four DVD boxset.
