A young executive

A young executive is leaving the office late one evening, when he finds the CEO standing in front of a shredder with a piece of paper in his hand.
“Listen,” says the CEO, “this is a very sensitive and important document here, and my secretary has gone for the night. Can you make this thing work for me?”
“Sure,” the young executive says.
He turns the machine on, inserts the paper, and presses the start button.
“Excellent, excellent!” says the CEO as his paper disappears inside the machine. “I just need one copy.”
