The popularity of "New Year's Rockin' Eve" also resulted in Clark making appearances on other television series to reference his role. During a Y2K-themed short in "The Simpsons 1999 Halloween special "Treehouse of Horror X", Clark made a cameo appearance hosting a New Year's Eve event in Springfield. The Y2K bug caused the emcee to melt, exposing him as a robot. In an interview following the episode's airing with its writer, Ron Hauge, Clark said that the episode gave the "biggest response" he had ever gotten from anything he had ever done. Clark made a further appearance during the pilot episode of fellow Matt Groening series "Futurama", "Space Pilot 3000", where Clark's head (as preserved in a jar) hosts "New Year's Rockin' Eve 3000". In the 1994 film "Forrest Gump", footage of Clark from the first edition of "New Year's Rockin' Eve" is seen on a television at a bar during a scene of the film taking place on New Year's Eve in 1972. "New Year's Rockin' Eve" was also the subject of an episode of the sitcom "Friends", "The One with the Routine", in which Janine Lecroix invites Joey, Ross, and Monica to attend a studio taping for "New Year's Rockin' Eve" as audience members.
