One day, a mechanical engineer, electrical engineer, chemical engineer,
and computer engineer were driving down the street in the same car when
it 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 enough gas."

The electrical engineer said, "I think there was a spark and something's
wrong with the electrical system."

All three turned to the computer engineer and said, "What do you think?"
