A salesman, an engineer, and a programmer drive a rental car up Pikes Peak. On the way down, the brakes fade, and the one driving manages to skid to a stop in a cloud of dust at the edge of a precipice. The salesman wants to call for a tow truck, the engineer wants to try to fix the brakes, but the programmer says: “No, first we should drive back up and confirm that we can reproduce the issue.”
