One day, a Mechanical Engineer, an Electrical Engineer, a Chemichal Engineer and a Software Engineer were driving down the street in the same car.
And, suddenly.......
The car broke down...
The mechanical Engineer said," I think q rod broke. We can check the rods."
The chemical Enggineer said,"The way it sputtered at the end, I don't think it's getting gas. We shall check the gas tank."
The Electrican Engineer said," I think there was a spark and something is wrong with the electrical system. We shall check the circuitry."
All three turned to the Software Engineer, and said,"What do you think?"

The Sofware Engineer said,"We shall get out of the car and get in again."
