engineers....

A mechanical, electrical and computer engineer were riding together to an engineering seminar when the car suddenly 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!"
