James Douglas Muir "Jay" Leno (born April 28, 1950) is an American stand-up comedian and television host.

From 1992 to 2009, Leno was the host of NBC's The Tonight Show with Jay Leno. Beginning in September 2009, Leno started a primetime talk show, titled The Jay Leno Show, which aired weeknights at 10:00 p.m., also on NBC. After The Jay Leno Show was canceled in January 2010 amid a host controversy, Leno returned to host The Tonight Show with Jay Leno on March 1, 2010.

In the 2001 The Fairly OddParents episode "Chin Up!", he began voicing the Crimson Chin, who is a blatant parody of Leno's infamously large chin. The Chin, whose real name is Charles Hampton Indigo was also a late-night talk show host when a radioactive guest bit his chin, further parodying Leno. In some of the Chin's later appearances, other versions of the hero would be introduced. Except for when the in-universe Adam West was cast as the Chin for a movie based on the character, Leno voiced all other versions of the Chin, ranging from decade counterparts throughout the Chin's history, to his evil counterpart, the Nega-Chin, who appeared in three episodes. In the episode "Lights...Camera...Adam!", Leno voiced himself interviewing Britney Britney, as the Chin crashed through his set.
