There are three engineers in a car, an electrical engineer, a
chemical engineer, and a Microsoft engineer. Suddenly the car just
stops by the side of the road, and the three engineers 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. Then, the Microsoft engineer, not
knowing much about anything, comes up with a suggestion. "Why don't
we close all the windows, get out, get back in, open the windows
again, and maybe it'll work!?"
