Bart and Lisa decide to help reunite father and son, but Hyman refuses to accept Krusty's career choice because he thinks Krusty abandoned his faith and family. To outsmart him, Lisa finds Judaic teachings that urge forgiveness, but Hyman refutes Lisa's arguments and refuses to reconcile with Krusty. In a last-ditch effort, Bart convinces him to abandon his stubborn ways by quoting Sammy Davis, Jr. — a Jewish entertainer like Krusty — and making a passionate plea about the struggles that the Jewish people have overcome. Bart's speech finally convinces Hyman that entertainers have a place in Jewish culture.
