Seems 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, but 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, no, I think we should take it
into town and have a specialist look at it."
        The programmer said, "OK, but first I think we should get back
in and see if it does it again."
