Since I've got finals coming up, here's a little finals humor:
The blonde co-ed showed up for her final exam totally unprepared. Fortunately, it was True/False. Unfortunately, she had no idea which was which. Undaunted, she pulled out a coin and started tossing it, marking "Y" for heads, and "N" for tails. Soon she started erasing and remarking and continued doing so until all the other students had finished and gone. The instructor finally came over to ask what was going on. She replied, "Oh, I finished the exam in a half hour. I'm just rechecking my answers!"
