The driver of a huge trailer lost control of his rig, and plowed into an empty toll booth, smashing it to pieces.
Some time after the driver had reported the damage, he watched as a repair truck pulled up and discharged a crew of workers. They picked up each broken piece of the wreckage and spread a creamy substance on it. Then they began fitting the pieces together.
In less than a half hour, they had the entire tollbooth reconstructed and looking good as new. "Astonishing!" said the truck driver to the crew chief. "What was the white stuff you used to stick all the pieces together?"
"Oh, that was tollgate booth paste."
