An eccentric philosophy professor gave a one question final exam after a semester dealing with a broad array of topics. The class was already seated and ready to go when the professor picked up his chair, plopped it on his desk and wrote on the board: "Using everything we have learned this semester, prove that this chair does not exist."
Fingers flew, erasers erased, notebooks were filled in furious fashion. Some students wrote over 30 pages in one hour attempting to refute the existence of the chair. One member of the class however, was up and finished in less than a minute.
Weeks later when the grades were posted, the rest of the group wondered how he could have gotten an A when he had barely written anything at all. His answer consisted of two words: "What chair?"
One day, a Mechanical Engineer, Electrical Engineer, Chemical Engineer and Computer Engineer were driving down the street in the same car.
The car broke down.
The Mechanical Engineer said, "I think a rod broke."
The Chemical Engineer said, "The way it sputtered at the end, I don't think it's getting gas."
The Electrical Engineer said, "I think there was a spark and something is wrong with the electrical system."
All three turned to the computer engineer and said, "What do you think?"
The Computer Engineer said, "I think we should all get out and get back in."
