Bart and Lisa try to reunite Krusty the Clown with his father.
Krusty the Clown has dinner with the Simpsons, and reveals that he is Jewish, his real name is Herschel Krustofsky, and he is estranged from his rabbi father. They parted ways over Krusty's becoming a clown instead of following his father and becoming a rabbi. Bart and Lisa see Krusty becoming depressed, and they take it upon themselves to reunite him with his father.
Krusty the Klown (finally) fulfills a promise to have dinner with the Simpsons, during which he reveals his Jewish heritage, and his estrangement from his father, who expected him to follow in his footsteps by becoming a Rabbi. Seeing how distraught he is, Bart and Lisa set out to reconcile Krusty with his father.—Tfilm78
