The Antartian reported for her university final examination which consisted of "yes/no" type questions. She took her seat in the examination hall and stared at the question paper for five minutes.
In a fit of inspiration, she took her purse out, removed a coin and started tossing the coin and marking the answer sheet - Yes for Heads and No for Tails. Within half an hour she was all done, whereas the rest of the class was still sweating it out.
During the last few minutes, she was seen desperately throwing the coin, muttering and sweating. The moderator, alarmed, approached her and asked what was going on. Her reply was, "I finished the exam in half and hour, but I'm rechecking my answers."
