A strong young man at a construction site was bragging that he could outdo anyone when it comes to pure strength.

He made a special case of making fun of one of the older workers at the job site. After several minutes of ranting, the older worker had had enough.

"Why don't you put your money where your mouth is and challenge me to a strength competition," he said. "I will bet an entire week's pay 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. Let's see what you got," the young boaster replied.

The old man reached out and grabbed the wheelbarrow by the handles. Then, nodding to the young man, he said,

"All right, hop in."
