This guy walks in to a bar. He has a few and gets loaded. Another guy says "Hey buddy, want ten bucks?" And of course, the reply is yes. He says "Either you screw a nun, or pull out a rottwieler's loose tooth. Your choice. Then I'll give you your ten bucks.." You gotta remember, this guy's drunk. He says he'll pick the rottweiler. So he goes in to a room and there's a bunch of banging around in the room and finally the guy walks out bleeding. He then says "Wow! That sure was tough. Will you pay me twenty buck if I go see the nun with the loose tooth?"
