text: Kaufman disliked sitcoms and was not happy with the idea of being in one, but Shapiro convinced him that it would quickly lead to stardom, which would earn him money he could then put into his own act. Kaufman agreed to appear in 14 episodes per season, and he initially wanted four for Kaufman's alter ego Tony Clifton. After Kaufman deliberately sabotaged Clifton's appearance on the show, however, that part of his contract was dropped.
  His character was given multiple personality disorder, which allowed Kaufman to randomly portray other characters. In one episode of Taxi, Kaufman's character came down with a condition that made him act like Alex Rieger, the main character played by Judd Hirsch. Another such recurring character played by Kaufman was Latka's womanizing alter ego Vic Ferrari.
  Sam Simon, who early in his career was a writer and later showrunner for Taxi, stated in a 2013 interview on Marc Maron's WTF podcast that the story of Kaufman having been generally disruptive on the show was "a complete fiction" largely created by Zmuda. Simon maintained that Zmuda has a vested interest in promoting an out-of-control image of Kaufman. In the interview Simon stated that Kaufman was "completely professional" and that he "told you Tony Clifton was him", but he also conceded that Kaufman would have "loved" Zmuda's version of events.
