> One year there were these two guys who were taking chemistry at Duke and who did pretty well on all of the quizzes and the midterms and labs etc., so well, that going into the finals they had a solid A. These two friends were so confident, that the weekend before finals week, they decided to go to a University party in another state. They did and had a great time.

However, with their hangovers and everything they overslept and didn't go home on Sunday, and arrived back on their campus on Monday. Rather than taking the final they went to their professor and explained to him why they missed the final. They told him they went to UVA for the weekend and had planned to come back in time to study, but they had a flat tire on the way back and didn't have a spare and couldn't get help for a long time and so were late getting back to campus. The professor thought this over and then agreed that they could make up the final the next day. The two guys were elated and relieved.

So they studied and the next day, they went to take the test. The professor put them in seperate rooms and gave each of them a test booklet and told them to begin. They looked at the first problem which was something simple about morality and solutions and was worth 5 points. "Cool" they thought, "this is going to be easy" They did that problem and then turned to the page. They were unprepared, however, for what they saw on the next page.

It said: #2 (95 points) Which tire?
