Recognise the man in the picture wearing the cap? That's Evander Holyfield, former Undisputed World Champion and bearer of a bitten ear courtesy of Mike Tyson. Only American television channel NBC, covering the London 2012 Olympics, did not know who he was.
Holyfield was one of a number of tourists interviewed outside of Buckingham Palace as the Americans continued to talk about that opening ceremony segment, with Daniel Craig as James Bond escorting Her Royal Highness Queen Elizabeth II to the Olympic Park.
One man thought the it was "wonderful", only the NBC crew didn't appear to recognise one of the United States' most decorated boxers (and an Olympic medalist) in recent memory.
