Fred and Bob were chatting in a pub and Fred noticed that everyone who came in said hello to Bob. "You know a lot of people, Bob," he said. "I know everyone," said Bob. "You can't know everyone." "I do." "Bet you don't know the Queen." To cut a long story short they travelled to London so that Bob could prove he knew the Queen and sure enough, they were invited in to have tea with her. "O.K, I'm impressed," said Fred, "but I bet you don't know the Russian President." A trip to Russia followed and Fred was gobsmacked when Dimitry Medvedev warmly embraced his old friend, Bob. "But I bet you don't know the Pope," said Fred. Fred stood in St Peter's Square, amazed to see Bob up on the balcony next to the Pope, when an American said to him, "Hey, who's that guy up there with Bob?"
