The strong young man at the construction site was bragging that he could outdo anyone in a feat of strength. He made a special case of making fun of one of the older workmen. After several minutes, the older worker had had enough. "Why don't you put your money where your mouth is?" he said. "I will bet a week's wages that I can haul something in a wheelbarrow over to that building that you won't be able to wheel back." "You're on, old man," the young guy replied.

The old man reached out and grabbed the wheelbarrow by the handles. Then he turned to the young man and said, "Alright. Get in."

Ha! Ha! Who needs strength when you've got smarts.
