The Boy and the Truck

My third grade teacher, who was also my first and second grade teacher, told a story about a truck that was a little too big and had gotten caught beneath a bridge, squeezed between the bridge and the pavement. No one could figure out how to free the truck until a boy came along, looked at the situation and said, "Why don't you just let some air out of the tires?" That story has always stuck with me.
