Judd Nelson and Bill Paxton star in this cult classic. Garbage man Marty (Nelson) tries his hand at stand-up comedy, failing miserably until a third arm mysteriously grows from his back. Gus, his accordion player friend, figures out a way to use the new arm and gets them signed with a sleazy talent agent. Just when success seems near, Marty's girlfriend leaves him - can the arm be far behind?
