Bart Simpson (voice of Nancy Cartwright) is a loyal fan of children's entertainer Krusty the Clown (voice of Dan Castellaneta), but when Krusty finally takes Bart up on an invitation to dine with his family, he learns the clown is not a very happy man. After Krusty is asked to say grace, the Simpsons discover that he's Jewish and that the source of his depression is his father, Rabbi Krustofski (voice of Jackie Mason), who disowned his son when he chose to go into show business rather than become a rabbi in accordance with family tradition. As Lisa (voice of Yeardley Smith) so eloquently puts it, "A man who envies our family is a man who needs help," so Bart and Lisa take it upon themselves to reunite Krusty with his father; they soon learn, however, that Rabbi Krustofski is a very stubborn man. "Like Father, Like Clown" first aired on October 24, 1991.
