A project manager, a mechanical engineer, and a computer scientist are on a road trip through the mountains. As they're going down a pass, the brakes suddenly fail. The car goes off the road and crashes down into the valley. A bit dazed, the three of them get out.
The project manager says, "Well, the best thing to do is to have a meeting and assess the situation."
The mechanical engineer replies, "Nonsense, I have my pocketknife, I'll fix the brakes with that."
Then the computer scientist comes along and says, "Why make it so complicated? Let's push the car back up the road, get in, and see if it happens again."
