A programmer, a marketing person, and a hardware engineer go on a camping trip. On the way down the mountain the car skids out of control and almost rolls off the cliff. The marketing person starts framing the story he will tell when he gets home. The hardware person opens the hood to look at the engine in order to understand what happened. The programmer says, "Let's take it up to the top of the hill and drive it back down to see if it happens again".
