Two college seniors had a week of exams coming up. However,
they decided to party instead. So, when they went to
the test, they decided to tell the professor that their
car had broken down the night before due to a very flat
tyre 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 the next morning, each boy was told to
go to separate classrooms to take the exam. Each shrugged
and went to 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 tyre it was."
