3 guys were riding in a car: a hardware technician, a systems analyst, and a programmer. The systems analyst is driving and when they come to a steep hill he finds that the brakes have failed and the car is accelerating out of control.
So, the driver pumps the emergency brake, down-shifts the gears, and rubs the wheels' rims against the curb. He finally wrestles the car to a stop. The three climb out and assess the situation.
Hardware tech: "Let's try and fix it. I'll crawl under the car and take a look. "
Systems analyst: "No. I think we should get someone qualified to fix it, a specialist in brakes."
Programmer: "Why don't we just get back in and see if it happens again?"
