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. We can check the rods."
The Chemical Engineer said, "The way it sputtered at the end, I don't think
it's getting gas. We shall check the gas tank."
The Electrical Engineer said, "I think there was a spark and something is wrong
with the electrical system. We shall check the circuitry."
All three turned to the computer engineer and said, "What do you think?"
The Computer Engineer said, "We shall get out of the car and get in again ."
