Four engineers in a car driving down the highway.... A mechanical engineer, an electrical engineer, a thermodynamic engineer & a software engineer. Suddenly the car isn't running right so they pull to the side of the road. The mechanical engineers says ""The engine sounds like it has a knock to it. I think we bent a valve."" The electrical engineer says ""No, it sounds more like a misfire. Check the wiring harness and the spark plugs."" The thermodynamics engineer says ""No, look at the temp gauge. It's overheating. Something's wrong with the cooling system."" The software engineer says ""You idiots. Just close the windows & open em back up again.""
