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, downshifts 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?"
