A Mechanical, Electrical and Computer Engineer were riding together to an Engineering Seminar; the car began jerking and shuttering.

The mechanical engineer, said, "I think the car has a faulty carburetor."

The electrical engineer said, "No, I think the problem lies with the alternator."

The computer engineer brightened up and said, "I know, let’s stop the car, all get out of the car and get back in again!"
