A clergyman walking down a country lane and sees a young farmer struggling to load hay back onto a cart after it had fallen off.
"You look hot, my son," said the cleric.
"why don't you rest a moment, and I'll give you a hand." "No thanks," said the young man.
"My father wouldn't like it." "Don't be silly," the minister said.
"Everyone is entitled to a break.
Come and have a drink of water." Again the young man protested that his father would be upset.
Losing his patience, the clergyman said, "Your father must be a real slave driver.
Tell me where I can find him and I'll give him a piece of my mind!
" "Well," replied the young farmer, "he's under the load of hay."
