A young man was hired by a supermarket and reported for his first day of work. The manager greeted him with a warm handshake and a smile, then gave him a broom and said,

"Son, your first job will be to sweep out the store."

"But I'm a college graduate," the young man replied indignantly.

"Oh, I'm sorry. I didn't realise that," said the manager. "Here, give me the broom -- I'll show you how."
