A college boy and his girlfriend went out the night before their major exams. Both of them were totally pissed out of their minds when

they got back home. The next day they were so hungover they



missed most of their class. When they finally showed up, their was only 15 min. left in class before papers had to be turned in. They told the professer that their cars tire popped and they couldnt flag down a ride. The professer uh huhed with sympathy and told them they could write the exam the next day. The next day they came in and were sent into different rooms. The cover of the test said, this will determine all I need to know. They opened the test and saw there was only one question. Which tire was it?
