Its always good to laugh

A truck driver saw a sign ahead of him that said 'low bridge ahead', before he knew it, the bridge was right in front of him and he got stuck, cars were backed up for miles. Finally a police car arrived, the officer got out of his car, walked around to the truck driver, put his hands on his hips and said, "Got stuck, huh?"  "No" the truck driver replied. "I was delivering this bridge and ran out of gas."
