Sophie shows Krusty her prized violin and plays a song for him. That night, Krusty plays in a poker game with Fat Tony, where he is dealt four aces with a king kicker, but is forced to bet Sophie's violin after running out of money and betting his Rolex watch, and loses the hand to Fat Tony, who had a straight flush (2-3-4-5-6 of diamonds). Sophie loses her trust in Krusty upon hearing the news, and Krusty turns to Homer for help; the two attempt to break into Fat Tony's mansion while a mafia summit is being held. They find a room filled with violin cases, but most of them are filled with weapons. They attempt to sneak out with the cases, but they fall to the ground and a mob shootout erupts around them; Krusty finds the violin, and the two escape. The next day, Krusty gives the violin back to Sophie, who is delighted to find that the case has been lined with money. The episode ends with Homer still being pursued by the mafia. Production The episode was written by John Frink and Don Payne and features guest stars Jay Mohr as Christopher Walken, Stephen King as himself, Amy Tan as herself, John Updike as himself and Joe Mantegna as recurring character Fat Tony. Drew Barrymore also guest-starred as Krusty the Clown's daughter in the episode. Fat Tony would later appear in the critically acclaimed "Trilogy of Error". The episode went into a cycle where it was written in season 11 and produced for season 12. Originally, Homer Simpson was the one who was surprised to have a long-lost daughter, but this was changed to Krusty as a suggestion from Mike Scully. During production Julie Kavner, the voice of Marge Simpson, went to Stephen King's radio station to record lines. Ian Maxtone-Graham was the one who suggested Jay Mohr as the real Christopher Walken could not make it to the recording. Some sources suggest Christopher Walken originally agreed to appear as himself. However, he then decided to demand a lot more money than the producers were willing to pay. Instead, Jay Mohr provided the voice of Walken. In the end credits, Jay Mohr is credited with the voice of Christopher Walken, and the credit says "Jay Mohr as Christopher Walken". This is the first time this has ever been done. Cultural references The episode title is a
