Bachelor Party (1984)

Tom Hanks stars as Rick Gassko, a bus-driving schlub who somehow gets engaged to Debbie (Tawny Kitaen), a rich socialite, in Bachelor Party (1984). But before he submits to the ball and chain, an insane bachelor party is thrown for him at a posh hotel. What follows is a cavalcade of hookers, drugs, debauchery, and even a barnyard animal for a kink. Tawney finds out about the skin-dig, of course, and skin-nanigans ensue. Since the film revolves around a bachelor party, there's a lot of female flesh. But Robert Prescott shows off his hairy ass to a very surprised couple in the car. Also, Gary Grossman and Brett Clark Baxter add some shirtless action during a couple hilariously sexy scenes. Bachelor Party will put a party in your underwear!
