A truck driver was drivingalong on the freeway. A sign comes up that reads "low bridge ahead." He tries to turn off but, before he knows it, the bridge is right there and he gets stuck under it. Cars arebacked up for miles. Finally, a police car comesup. The cop gets out of his car and walks around to the truck driver, puts his hands onhis hips and says, "Got stuck huh?" The truck driver says,"No, I was delivering this bridge and ran out of gas"
