Two college seniors had a week of exams coming up. They decided to party instead. Their biggest exam was on Wednesday, and they showed up telling the professor that their car had broken down the night before due to a very flat tire and they needed a bit more time to study.
The professor told them that they could have another day to study. That evening, both of the boys crammed all night until they were sure that they knew just about everything.
Arriving to class early the next morning, each boy was told to go to two separate classrooms to take the exam. Each
boy just shrugged and went to the two different parts of the building.
As each sat down, they read the first question.
"For 5 points, explain the contents of an atom."
At this point, they both thought that this was going to be a piece of cake, and answered the question with ease.
Then, the test continued.
"For 95 points, tell me which tire it was"...
