See, prison skiing was the only thing that would keep Dante and Tyrone from turning Matt's asshole into truffle butter.

when guys in jail don't see any girls in years, they get desparate. They fight with their cellmates, and the winner gets to fuck the other in the ass. Often the bitch has to dress and act like a girl.
