A policeman cruising past a pub after closing time notices two motor bikes still parked out the front. He goes round the back of the pub only to find two bikers, one with his fingers up the butt of the other. "So what's going on here?" he 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!"
