A truck driver was driving along
on the
freeway. A sign comes up that reads “low bridge ahead.” Before
he
knows it the bridge is right ahead of him and he gets stuck under
the
bridge.

Cars are backed up for miles.

Finally, a police
car comes up. The cop gets out of his car and walks
around to the
truck driver, puts his hands on his hips and says, “Got
stuck,
huh?”

The truck driver says, “No, I was delivering this bridge and ran
out
of gas.”
