Photograph of Bozo the Clown character with open-mouth smile on green background.
The WGN-TV Chicago Bozo Show debuted in 1960 and continued until 2001. Bob Bell (pictured) played the original "Bozo the Clown" from 1960-1984. He was inducted into the International Clown Hall of Fame in 1996. Simpson's actor Dan Castellaneta cites Bob Bell's Bozo as the influence for his Krusty the Clown character voice.
