A computer engineer, a systems analyst, and a programmer were driving down a mountain when the brakes failed. They screamed down the mountain, gaining speed, and finally managed to grind to a halt, more by luck than anything else, just inches from a thousand foot drop to jagged rocks. They all got out of the car.
The computer engineer said, "I think I can fix it."
The systems analyst said, "No, I think we should take it into town and have a specialist look at it."
The programmer said, "Okay, but first I think we should get back in and see if it does it again."
