Herschel Shmoikel Pinchas Yerucham Krustofski, better known by his stage name, "Krusty the Clown," or simply as "Krusty", is the cynical, burnt out, addiction-riddled smoking clown host of Bart and Lisa's favorite TV show, The Krusty the Clown Show.
Krusty is a hard-living entertainment veteran who has been down and out
several times (always being rescued by the Simpson children) and remains
addicted to cigarettes and alcohol (and, in one episode, Percodan). He also
seems to suffer from bipolar disorder. Krusty lives in his mansion in the upscale residential area of
"Springfield Heigths", which is also resided by Mob boss "Fat" Tony
D'Amico and actor Troy McClure.
Krusty's father is Rabbi Hyman Krustofski, and he lived with his father in the Jewish community. Through his unnamed mother, Krusty is supposedly an older half-brother to actor Luke Perry, and Mia Farrow is his ex-wife. He has several illegitimate children, one of which is named Sophie.
