 Rabbi Krustofsky then appears and tells Krusty that Jews do not believe in Heaven, and thus he should do more to help others.An act of kindness does not seem to make him happier, but Bart takes Krusty to the synagogue, where Rabbi Krustofsky's favorite rabbi recites Krusty's jokes on religion.Krusty therefore deduces that his father did find him funny, and sees him again in Jewish Heaven, where Jesus turns Dangerfield's water into a Bloody Mary.
