A strong young man at a 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. ‘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 braggart replied. ‘Let’s see you do it.’

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.’
