A first year lawyer was leaving the office late one evening when he found the managing partner standing in front of a shredder with a piece of paper in his hand.
"Listen," said the partner, "This is a very sensitive and important document here, and my secretary has gone for the night. Can you make this thing work?"
"Certainly," said the associate. He turned the machine on, inserted the paper, and they watched it disappear into the shredder.
"Excellent, excellent" said the partner. "I only need one copy."
