Maxine, the platinum blonde, reported for her final examination which
consisted of Yes / No answers.

She took her seat in the examination hall, stared at the question paper,
and then in a bit of inspiration, took a quarter out of her purse. She
started tossing the coin and marking the answer sheet "Yes" for heads
and "N" for tails.

Within 30 minutes she was all done whereas the rest of the class was
still sweating it out. During the last few minutes of the exam period,
Maxine frantically started flipping the coin again.

The moderator, concerned about what she was doing, stopped by her desk
and asked if she was ok.

"Oh yes, I'm fine. I finished the exam a half hour ago--but," explaining
the frantic coin tossing, "I'm going back thru and checking my answers!"
