During a tear-filled dinner at the Simpsons' house, Krusty the Clown reveals that he is the estranged son of an Orthodox Jewish Rabbi. It seems that Krusty's father, Rabbi Krustofski, never accepted his son's profession, and disowned him years ago. Bart and Lisa decide to reunite the two men, but find that getting the Rabbi to agree to a meeting is nearly impossible. After endless research by Lisa, and repeated negotiations by Bart, the Rabbi agrees to meet with his clown son, and the two men are reunited and appear together on The Krusty the Clown Show.
