The Simpsons - Season 7 Episode 15 -

Bart gets a check he wanted signed by Krusty back stamped. As Krusty was supposed to autograph it, Bart wants it taken back to sign, but inadvertently reveals Krusty as a tax fraud. Krusty's lifestyle is stripped down to that of an average citizen, his show ruined and most of his possessions sold in an auction. Bart is mad at himself, particularly after a sobbing Krusty commits suicide by piloting his plane, the I'm-Onna-Rolla-Gay, into a mountainside. Bart sees visions of Krusty everywhere, but are they illusions or real life?
