Stuck In A Bridge

A truck driver was driving along on the freeway. A sign appeared that read "Low bridge ahead." Before he knew it the bridge was right ahead of him, and he couldn't avoid getting stuck under the bridge. Cars became backed up for miles.

Finally, a police car approaches. The police officer climbs out of his car and walks around to the truck driver. The officer puts his hands on his hips and says, "Got stuck huh?"

The truck driver replies, "No, I was delivering this bridge when I happened to run out of gas."
