One day a secretary is leaving on her lunch break, and she notices her boss standing in front of a shredder with a clueless look on his face. The secretary walks up to him and asks if he needs help.
"Yes!" he says looking and sounding relieved, "This is very important."

Glad to help, she turns the shredder on and inserts the paper. Then her boss says, "Thanks, I only need one copy."
