Flat tire

The Trucker and the Waitress
The Trucker and the Waitress A trucker came into a truck stop coffee shop and placed his order. He said, "I want three flat tires, a pair of headlights and pair of running boards." The brand new blonde waitress, not wanting to appear stupid, went to the kitchen and said to the cook, "This guy out there just ordered three flat tires, a pair of headlights and a pair of running boards. What does he think this place is, an auto parts store?" "No," the cook said. "Three flat tires mean three pancakes, a pair of headlights is two eggs sunny side up, and running boards are 2 slices of crisp bacon." "Oh, OK!" said the blonde. She thought about it for a moment and then spooned up a bowl of beans and gave it to the customer. The trucker asked, "What are the beans for, Blondie?" She replied, "I thought while you were waiting for the flat tires, headlights and running boards, you might as well gas up!"
But Professor, We Had a Flat Tire
But Professor, We Had a Flat Tire At NC State University, there were four sophomores taking Organic Chemistry. They did so well on all the quizzes, midterms and labs that each had an "A" so far for the semester. These four friends were so confident, that the weekend before finals, they decided to go up to the University of Virginia and party with some friends there. They had a great time. However, after all the hard-partying, they slept all day Sunday and didn't make it back to Raleigh until early Monday morning. Rather than taking the final then, they decided to find their professor after the final and explain to him why they missed it. They explained that they had gone to UVA for the weekend with the plan to return Sunday to study, but, unfortunately, they had a flat tire on the way back, didn't have a spare, and couldn't get help for a long time. As a result, they missed the final. The Professor thought it over and then agreed they could make up the final the following day. The gals were elated and relieved. They studied that night and went in the next day at the time the professor had told them. He placed them in separate rooms and handed each of them a test booklet, and told them to begin. They looked at the first problem, worth 5 points. It was something simple about free radical formation. "Cool," they thought at the same time, each one in her separate room, "this is going to be easy." Each finished the problem and then turned the page. On the second page was written: For 95 points: Which tire?
