A tractor-trailer rig was stuck under an underpass. Soon a large crowd gathered to watch the show and jeer as the driver struggled to pull it free. He put the rig into low, but the trailer would not budge. Then the driver put the truck in reverse, floored the accelerator, and went nowhere! A small boy was standing in the crowd; he went up and banged on the cab door. "I think can help!" he said. The angry driver yelled back, "What could you know about it?" "Not much maybe," the boy said quietly, "but if I was you I would let the air out of the tires to free the trailer.
