There are four engineers travelling 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", 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 earthing problem", says the electrical engineer, "or maybe a faulty plug lead."

They 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?"

A Software Engineer and a Mechanical Engineer were driving down a steep mountain road when suddenly the brakes on their car failed. The car careered almost out of control down the road, bouncing off the crash barriers, until it miraculously ground to a halt scraping along the mountain side.
"I've got my Swiss Army knife with me, said the Mechanical Engineer,and in no time at all I can strip down the car's braking system, isolate the fault, fix it, and we can be on our way."

"Well, I don't know", said the Software Engineer, "Before we do anything, I think we should push the car back up the road and see if it happens again."
