FOUR ENGINEERS TRAVELLING IN A CAR
		----------------------------------

	       There are four engineers traveling in a car; a
               mechanical engineer, a chemical engineer, an
               electrical engineer and a computer engineer. The car
               breaks down.

               "Sounds to me as if the pistons have seized. We'll have
               to strip down the engine before we can get the car
               working again", says the mechanical engineer.

               "Well", says the chemical engineer, "it sounded to me
               as if the fuel might be contaminated. I think we should
               clear out the fuel system."

               "I thought it might be an grounding problem", says the
               electrical engineer, "or maybe a faulty plug lead."

               They all turn to the computer engineer who has said
               nothing and say: "Well, what do you think?"

               "Ummm - perhaps if we all get out of the car and get
               back in again?"
