A policeman cruising past a bar after closing time notices two motor bikes still parked out front. He goes around the back of the pub only to find two bikers, one with his fingers up the ass of the other. So, what's going on here?, the cop asks. The biker replies, My mate here has had too much to drink and I'm trying to make him vomit. The cop says, I think you should be sticking your fingers down his THROAT! The biker replies, That's what I'm going to do next!
