A young executive was leaving the office at 6pm when he found the Boss standing in front of a shredder with a piece of paper in hand.”Listen,” said the Boss, “this is important, and my secretary has left already. 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 Boss as his paper disappeared inside the machine.”I just need one copy.”
