A boy goes to the cinema. He buys a ticket and enters. However, after just a few minutes, he comes out. He buys a second ticket and goes in again. A short while later, he emerges once more and purchases a third ticket. Minutes after that, he comes out for a third time and asks for another ticket.
The ticket seller asks him, "Why are you buying so many tickets? Are you meeting different friends inside each time?"
"No, I'm not," the boy replies. "But a large woman at the door always stops me and tears my ticket up."
