The boss was standing in front of the paper shredder with a confused look on
his face.  I asked if he needed any help and he said, "Yeah, how does this
thing work?"

I took the papers from him and fed them into the shredder, demonstrating how it
worked.  He just stood there a moment with another confused expression.

So I asked, "Any questions?"

"Yeah," he said, "where do the copies come out?"
