A bit of a giggle

There are three engineers driving a car across country, a chemical engineer, an electrical engineer and a software engineer from Microsoft.
The car breaks down out in the middle of the desert. They start arguing about what is wrong with the car and how to fix it.
The chemical engineer says, "maybe the fuel solidified somewhere in the engine, let's flush it and see if that works".
The electrical engineer says "no, no, no, it's obviously a short in the wiring because the air conditioner wasn't working".
Then the software engineer says "why don't we close the windows, open them again and see if it starts?"
