The setting is Ohio State University about six or seven years ago in a huge lecture hall (approximately 1000 students) for a Calculus final.Apparently this particular calculus teacher wasnt very well liked. He was one of those guys who would stand at the front of the class and yell out how much time was remaining before the end of a test, a real charmer.Since he was so busy galavanting around the room making sure that nobody cheated and that everyone was aware of how much time they had left before their failure on the test was complete, he had the students stack the completed tests on the huge podium at the front of the room. This made for quite a mess, remember there were 1000 students in the class.During this particular final, one guy entered the test needing a decent grade to pass the class. His only problem with Calculus was that he did poorly when rushed, and the lecturer standing in the front of the room, barking out how much time was left before the tests had to be handed in, didnt help him at all.He figured he wanted to assure himself of a good grade, so he hardly flinched when the professor said, Pencils down and submit your scantron sheets and work to piles at the front of the room.Five minutes turned into ten, ten into twenty, twenty into fourty, and almost an hour after the test was officially over, our friend finally put down his pencil, gathered up his work, and headed to the front of the hall to submit his final. The whole time, the professor had been sitting at the front of the room, strangely waiting for the student to complete his exam.What do you think youre doing? the professor asked as the student stood in front of him about to put down his exam on one of the neatly stacked piles of exams. It was clear that the professor had waited only to give the student a hard time.Turning in my exam, retorted the student confidently.Im afraid I have some bad news for you, the profesor gloated, Your exam
