Santa reported for his university final examination, which consists of "Yes/No" type questions. He takes his seat in the examination hall, stares at the question paper for five minutes, and then in a fit of inspiration takes his purse out, removes a coin and starts tossing it, marking the answer sheet Yes for Heads and No for Tails.
Within half an hour he is all done whereas the rest of the class is sweating it out. During the last few minutes, he is seen desperately flipping the coin, muttering and sweating.
The moderator, alarmed, approaches his and asks what is going on.
Santa replies, "I'm rechecking my answers and I don't think I did very good".
