The driver of a huge tractor trailer lost control of his rig and plowed into an empty tollbooth, smashing it to pieces. He climbed down from the truck and surveyed the wreckage.
Within a matter of minutes, another truck pulled up and unloaded a crew of workers. The men picked up each broken piece of the former tollbooth and spread some kind of creamy substance on it. Then they began fitting the pieces together. In less than half an hour they had the entire tollbooth reconstructed and good as new.
"Astonishing!" the truck driver said to the crew chief. "What was that white stuff you used to get all the pieces together?"
The crew chief said, "Oh, that was tollgate booth paste."
