London Sights
It's amazing how much of London has been influenced by other countries.  The folks will tell you they are a bit pompous, maybe it's because very few locals here are actually Brits.
I can never tell what time it is
A real life Beefeater with the Tower Bridge in the background and the famous English fog.  These guys hang out at the Tower of London.
These guys also hang out at the Tower of London which is/was a museum, jail, place of execution, munitions dump, housing, the home of the Crown Jewels and oh yeah, the Kings home address once in a while. 
Almost 3000 diamonds in the shiny piles to the left and right.  Mr De Beers is loaning them to the Tower because he's a nice guy and he wanted to show how many diamonds it took to build a crown.
Is my hotel's toilet any better than this one?  This one is more than 3 hundred years old.  The results get piped out into the moat around the Tower.  After a few years, there was 6 ft of "stuff" in the moat when the river receded daily.  Ever wonder why they had the Black Plague?
