A mechanic, an engineer, and a programmer are driving to Las Vegas.
Halfway across the desert, the car conks out.
The mechanic says "I think we're out of gas. We could walk to a gas station."
The engineer says "I think we exceeded the heat tolerance of the radiator, and it overheated. We should just wait and see if it runs again after it cools down."
The programmer says "Let's all get out and get back in again!"
