1691. Krusty the Clown

Herschel Shmoikel Pinchas Yerucham Krustofski,^[1] better known by the stage name Krusty the Clown, is a fictional character in the animated television series The Simpsons. He is voiced by Dan Castellaneta. He is the long-time clown host of Bart and Lisa's favorite TV show, a combination of kiddie variety television hijinks and cartoons including The Itchy & Scratchy Show. Krusty is often portrayed as a cynical, burnt out, addiction-riddled smoker who is made miserable by show business but continues on anyway. He has become one of the most common characters outside of the main Simpson family and has been the focus of several episodes, most of which also spotlight Bart.
Krusty was created by cartoonist Matt Groening and partially inspired by Rusty Nails, a television clown from Groening's hometown of Portland, Oregon. He was designed to look like Homer Simpson with clown make-up, with the original idea being that Bart worships a television clown who looks like his own father. His voice is based on Bob Bell, who portrayed WGN-TV's Bozo the Clown. Krusty made his television debut on January 15, 1989 in the Tracey Ullman Show short "The Krusty the Clown Show".
