One day， a Mechanical Engineer， Electrical Engineer， Chemical Engineer and Computer Engineer were driving down the street in the same car.
The car broke down.
The Mechanical Engineer said “I think a rod broke.”
The Chemical Engineer said “The way it sputtered at the end， I think it's not getting gas.”
The Electrical Engineer said “I think there was a spark and something is wrong with the electrical system.”
All three turned to the computer engineer and said， “What do you think？”
The Computer Engineer said， “I think we should all get out and get back in.”
