There are four engineers traveling in a car: a mechanical engineer, a chemical engineer, an electrical engineer, and a software engineer ...who works on Microsoft Windows.
The car breaks down and they all have suggestions on what to do.
"Sounds to me as if the pistons have seized," says the mechanical engineer. "We'll have to strip down the engine before we can get the car working again."
"I disagree," says the chemical engineer. "It sounded to me as if the fuel might be contaminated. I think we should clear out the fuel system."
"I thought it might be a grounding problem," says the electrical engineer, "or maybe a faulty plug lead."
They all turn to the software engineer, who has said nothing so far.
"Well?" they all say to the geek. "What do you think?"
"Well," the Microsoftie suggests, "perhaps if we all get out of the car and get back in again...?"
