The strong young man at the construction site was bragging that he could out do 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 enough. He asked "Why don't you put your money wher e your mouth is,"? and 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 braggart replied. "Let's see what you got."The old man reached out and grabbed the wheelbarrow by the handles. Then, nodding to the young man, he said,
"All right, Dumb Ass, get in."
Thanks Richard, funny stuff...
