Paddy did not study for his university examination, which consisted of a series of “True/False” type questions. When the examination began, he just stared at the test for what seemed like an eternity. In a fit of inspiration, Paddy started tossing a coin and marking the answer sheet, “Yes” for heads and “No” for tails. Within minutes he was all done, whereas the rest of the class was still sweating it out. However, during the last few minutes, Paddy was once again tossing the coin, muttering and sweating. The moderator, alarmed, approached him and asked what was going on. Paddy replied, “I finished the exam half an hour ago, but I’m re-checking my answers.”
