A truck driver was driving along on the freeway and noticed a sign that read: Low Bridge Ahead. Before he knew it, the bridge was right in front of him and his truck got wedged under it. Cars got backed up for miles.
Finally a police cruiser arrives. The policeman got out of his car and walked over to the truck driver, put his hands on his hips and said, "Got stuck, huh?"
The truck driver said, "No, I was delivering this bridge and I ran out of gas."
