One of the many tourist attractions in London are the castle guards - at Buckingham Palace and at the homes of the various members of the Royal Family.  One of those residences is Clarence House.  Over the years Clarence House has been the home of Queen Elizabeth, the Queen Mother, Prince Charles and his wife Camilla Parker Bowles and Prince Harry.  It was also the official residence of Prince William until he was married last year.

Guards are on duty outside of Clarence House 24 hours a day, 365 days a year.  They're pretty stoic until you step over the line....or in this case when you touch the fence.  Check out to see what happens when a couple of boys go a little too far for this guard's tolerance.
