Three students stayed in mexico for 2 nights at a freinds house. They all had a good time, but the test in their college back in California was on the 3rd day. They decided to stay another night. When they got back on the fourth day, they told their proffessor that one of their tires had popped and the reason they couldn't make it was the lack of a spare tire. The scientist excused the abscence of them at the test and let them take it a day late. The three student were given a room each for the test. The first question was for 15 points and was multiple choice. One of them thought "This is going to be easy!" The next question asked "Witch tire popped?"
