Today, I discovered an "undo" button on the office shredding machine. I'll try to remember the camera for tomorrow so I can prove I'm not making this up (who knew that the day would come when my word was not longer good enough).
I gotta try to work out how I can see the shredder working in reverse - I can't imagine how it's going to join up all those little strips of paper and return them back to the original document.
