Three engineers are riding down the road in a car. Suddenly, the car begins to develop
trouble. It's sputtering and it sounds like it's going to stall.
The first engineer is a chemical engineer. He says, "It could be something in the fuel
line. Lets put an additive into the gas and maybe that will take care of the problem."
The second engineer is an electrical engineer. She says, "It could be something in the
electrical system. Let's replace the wires and the distributor cap. Maybe that will take
care of the problem."
The third engineer is a software engineer from Microsoft. He says, "It could be that
we have too many windows open. Let's close all the windows, turn off the car, then
restart the car and open all the windows again. Maybe that will take care of the problem."
