Component Jokes

Four engineers were travelling by car to a seminar, when unfortunately, the vehicle broke down. The chemical engineer said "Obviously, some constituent of the fuel has caused this failure to occur." The mechanical engineer replied "I disagree, I would surmise that an engine component has suffered a catastrophic structural failure." The electrical engineer also had a theory. "I believe an electrical component has ceased to function, thereby causing an ignition malfunction." The software engineer thought for some time. When at last he spoke he said "What would happen if we all got out and then got back in again?"
