A little off the topic, but funny none the less.
Arthur your signature says: "Whoever said 'nothing is impossible' never tried to slam a revolving door."

I can honestly say that I have successfullyslammed a revolving door.My buddy and I were in Toronto for the Rolling Stones concert and we were running around the city trying to find a hotel room.We were coming out of this one nice hotel, may have been a Hilton, Ican'treally remember, and being the immature reckless teens we were I thought it would be funny if I tried to slam back the revolving door as he tried to come through behind me...well the force of me pushing back and him pushing forward caused the door to completely colapse and fold up like a lawn chair. We took off running down the street and never looked back!
