Three guys are driving across Death Valley, when suddenly billows of steam start coming from under the hood.  They bring the car to a stop.

The first guy (a physicist) says, "Just what I  was afraid of. According to my calculations, given the ambient temperature,  the thermal conductivity of the engine housing can't disipate the heat generated by the engine.  We're doomed!"

"Wait a minute," says the second guy (a hardware engineer).  "It's probably the fan belt.  Look, I have a pocket knife here, and I can cut strips from the seat cover to make a temporary fan belt.  It'll at least get us to the nearest garage."

"Hey guys," says the third (a software engineer).  "Why don't you just try turning off the engine and turning it back on...Maybe it'll work."
