The Simpsons Crossovers
Homer and Bart Simpson made a brief appearance in "Dial M for Mother". During an interview with Geraldo Rivera, Jay is asked about talking over the heads of his audience and does just that in his answer. An annoyed family watching changes the channel to The Simpsons, where Homer—after stepping on a rake—exclaims, "D'oh!" and Bart replies, "Ay caramba!" The family's father comments, "Now, this I understand."
Jay had a guest appearance in an episode of The Simpsons titled "A Star Is Burns", presiding over a local film festival. This episode caused some conflict between Simpsons creator Matt Groening and executive producer James L. Brooks. Groening, believing the episode was little more than a thirty-minute advertisement for one of Brooks's less successful projects, had his credit removed from the episode and did not appear on its DVD commentary. When Jay enters the Simpson household, Bart is watching a Flintstones-Jetsons crossover show, which he criticizes; he then praises Jay and Coming Attractions/The Critic, before shuddering and saying to himself "I feel so dirty." At the end of the episode, as he is leaving for New York, Jay offers the Simpsons to appear on Coming Attractions/The Critic, but Bart declines, saying, "Nah, we're not going to be doing that." Jay has yellow skin when he appears on The Simpsons but pink skin on The Critic.
Jay appeared briefly on The Simpsons a few more times. In the episode "Hurricane Neddy," he was in an insane asylum apparently unable to say anything more than his catchphrase (Doctor: "Yes, Mr. Sherman. Everything stinks.") In the episode "The Ziff Who Came to Dinner", he is seen at Moe's Tavern with all the other characters on the show that Lovitz voices or has voiced.
