"Helping your father" joke

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."
