A computer engineer, a systems analyst, and a programmer were driving down a mountain when the brakes gave out. 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, "i think we should push it back up the hill and see if it does it again."
