Lemony Lickit's a Series of Horny Events

Lemony Lickit's a Series of Horny Events is a pornographic movie filmed by the Springfield Mafia.

History
Homer had run up a large gambling debt with the Springfield Mafia. Unable to pay, Homer agreed to let them make a pornographic movie in the Simpson home in order to satisfy the debt. Homer arranged for Marge and the kids to be gone by sending them to Santa's Village. The Mafia and a film crew from Gentleman's Relief Productions then showed up and began shooting.

During a scene that involved two spacesuit-clad women on the couch, the production was interrupted when Carl and Lenny happened by. Carl recognized the actresses and asked if they were shooting a reunion of Fahrenheit Nine on One. The director decided to give Lenny and Carl roles in the film, and shooting continued.

Production was interrupted a second time (this time for good) by the return home of Marge and the kids. Marge, outraged at the goings-on, confronted Homer: "Are you making a snuggle movie in our home?!"
