An electrical engineer, a chemical engineer and a Microsoft software engineer are driving together. Suddenly, the car just stops by the side of the road.
The electrical engineer says, "It's probably the car's internal electronics. We should check all the wiring and maybe we can trace where a fault might have occurred."
The chemical engineer says, "Maybe the fuel is becoming emulsified and it's getting blocked somewhere."
The Microsoft software engineer says, "If we close all the windows, get out, get back in, then open the windows again, maybe it'll work!"
