Office help

A man with a piece of paper in his hand comes into an office where another man is sitting next to a shredding machine.
"Do you know how to operate this thing?" he asks. "I have an important paper here and I want to make sure this is done right."
"Sure," the other man answers. "Just put the paper in here and press this button."
The first man does so, saying, "Great. And where do the copies come out?"
