A young executive was leaving the office at 6 pm when he found the CEO standing in front of a shredder with a piece of paper in hand.
"Listen," said the CEO, "this is important, and my secretary has left. Can you make this thing work?
"Certainly," said the young executive. He turned the machine on, inserted the paper, and pressed the start button.
"Excellent, excellent!" said the CEO as his paper disappeared inside the machine. "I just need one copy."
