Redneck I know exactly what you mean about gullable foreigners, I was in London for a day and walked past Buckingham Palace, a group of Canadian tourists overheard me talking about the Coldstream Guards outside the Palace and began swarming around me. Before I could do anything or say anything they were having photos taken of me and them shaking hands, I couldn't really say I wasn't a member of the Royal Family after all that, they were so happy and I liked tha attention really.
There was also another incident with a group of Japanese tourists, I was walking with a friend of mine and immediately a group came up to us and started taking photographs, the friend resembles John Major the British Prime Minister before Tony Blair came to power, again I thought it heartless to inform them that he wasn't in fact John Major and I wasn't a Member of Parliament.
The joys of tourists.
