There are three engineers in a car: an electrical engineer, a chemical engineer and a Microsoft engineer. Suddenly, the engine stops. The engineers sit by the side of the road, and look at each other wondering what could be wrong. The electrical engineer suggests stripping down the electronics of the car and trying to trace where a fault might have occurred. The chemical engineer, not knowing much about cars, suggests that maybe the fuel is becoming emulsified and getting blocked somewhere. The Microsoft engineer, not knowing much about anything, suggests: "Why don't we close all the windows, get out, get back in, open the windows again, and maybe it'll work?"
