When I worked at St. Thomas' Hospital in London
my mate's Mum came into our lab which overlooked the River Thames.
"That's a lovely building over there," quoth she, "what is it?"
"Nothing important," says my mate, "only the Houses of fucking Parliament."

Edit - Just remembered. I very often used to get asked on Westminster Bridge by visiting persons from Dumbfuckistan where Big Ben was? I'd reply in the Clock Tower - it's the bell, of course. I also got asked a lot to take pictures of Japanese tourists with the tower in the background. The thought of them getting their holiday snaps back from the Tokyo Boots with their little heads cut off still amuses me.... Serves 'em right for the Burma Railway....
