<P> Only a few of these shorts have been released on DVD . "Good Night" was included on The Simpsons Season 1 DVD . Five of these shorts were later used in the clip - show episode "The Simpsons 138th Episode Spectacular" on the half - hour show, which was released on the Season 7 DVD . These five shorts were "Good Night", which was featured in its entirety, and portions of "The Perfect Crime", "Space Patrol", "World War III", and "Bathtime". In "You Kent Always Say What You Want", the short "Family Portrait" replaces the entire opening sequence in celebration of the 400th episode . In June 2013, it was reported that FXX is trying to acquire the shorts for an October Simpsons app, "Simpsons World". </P> <P> The version of the Simpson family from the shorts was depicted as ghosts haunting the Simpsons house in the season twenty six episode "Treehouse of Horror XXV". </P> <P> When producer James L. Brooks was working on the television variety show The Tracey Ullman Show, he decided that he wanted to include short animated wraparounds before and after the commercial breaks . Having seen one of cartoonist Matt Groening's Life in Hell comic strips, Brooks asked Groening to pitch an idea for a series of animated shorts, which Groening initially intended to present as his Life in Hell series . Groening later realized that animating Life in Hell would require the rescinding of publication rights for his life's work . He therefore chose another approach while waiting in the lobby of Brooks's office for the pitch meeting, hurriedly formulating his version of a dysfunctional family that became the Simpsons . He named the characters after his own family members, substituting "Bart" for his own name . Bart was modeled after Groening's older brother, Mark, but given a different name which was chosen as an anagram of "brat". The stories were written and storyboarded by Matt Groening . The family was crudely drawn, because Groening had submitted basic sketches to the animators, assuming they would clean them up; instead they just traced over his drawings . The animation was produced domestically at Klasky Csupo, with Wesley Archer, David Silverman, and Bill Kopp being animators for the first season . After season one, it would be animated by Archer and Silverman thereafter . Gyorgyi Peluce was the colorist and the person who decided to make the characters yellow . </P> <P> The actors who voiced the characters in the short later reprised their roles in The Simpsons series . Dan Castellaneta performed the voices of Homer Simpson, Grampa Simpson, and Krusty the Clown . Homer's voice sounds different in the shorts compared to most episodes of the half - hour show, as Castellaneta originally tried to impersonate Walter Matthau . Although he would retain this characteristic through the early episodes of the regular series, it was gradually dropped as Homer's personality evolved away from that of a stereotypical sitcom father . The producers of the show were in need of someone to do voiceovers, so rather than hire actors, they asked Castellaneta (who had already done some voice work) and Julie Kavner, both members of the Ullman Show cast, to do it . The kids still needed voices, and Nancy Cartwright, a journeyman voice actress, came in to audition . She recalled that "I was already doing voicework for eight different shows at the time and thought this would just be another job . They originally wanted me for Lisa's voice, but I thought' Nah, I don't want to be the boring middle child, I want to be a bratty 10 - year old boy .' So as soon as I gave a demonstration, (Brooks and Groening) hired me on the spot ." Some time later, Yeardley Smith, a 22 - year - old B - movie actress whose most notable accomplishment to date was featuring in the notorious 1986 Stephen King film Maximum Overdrive, was brought in to do Lisa's voice . The recording of the shorts was often primitive; according to Cartwright, the dialogue for the Ullman shorts was recorded on a portable tape deck in a makeshift studio, which consisted of the video engineer suite, above the bleachers on the Ullman show set . While most of the characters' personalities are similar to what they are in the series, Lisa is simply a clone of Bart and did not have a distinct personality until a few episodes into the regular series . </P>
