Peter walks into a room with his friends all tied up and the two men from the scene being spoofed from this film, he then slices into one of them with a samurai sword, spoofing the scene where Bruce Willis' character kills a rapist in this movie.
We see Peter on a raft in the middle of the sea with a beard, dressed in rags. He is shouting "WILSON!" at a volleyball with a face on it just like Wilson from this film.
