A software engineer, a mechanical engineer, and an electrical engineer are carpooling to work, when suddenly the car stops running and they pull over.
The mechanical engineer says, "I think it's a problem with the engine. I'll have to get out and inspect."
The electrical engineer says, "No, no. It's got to be an electrical issue. I will grab my meter and troubleshoot to find out what is going on."
The software engineer says, "Nuts to all that. Let's just get out and get back in again."
