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