A 21-year-old is hired by a hardware store. He shows up for his first day of work at 8 AM sharp.
The boss welcomes him, then hands him a broom.
"First, sweep out the store. Then I'll show you where the window cleaning equipment is."
"Sir," the young man protests. "You can't be serious. I'm a college graduate."
"Oh, sorry," says the manager, pointing to the broom. "No problem. I can show you how that thing works."
