An electrical engineer, a mechanical engineer, and a software engineer are on a road trip to an academic conference when the car suddenly sputters and dies.

"It must a short in the wiring!" proclaims the electrical engineer.

"Of course not, it's probably a stuck valve," responds the mechanical engineer.

"Nonsense, both of you," says the computer engineer, "all we must do is get out of the car and then back in again."
