As they ride toward Buckingham Palace, each is looking sideways and waving to the thousands of cheering Brits lining the streets. All is going well, when suddenly the right rear horse lets fly with the most horrendous, earth-rending, eye-smarting blast of gastronomic flatulence ever heard in the British Empire, including Bermuda, Tortola and the Falkland Islands. It shakes the coach. Uncomfortable, but under control, the two dignitaries of state do their best to ignore the whole incident, but then the Queen decides that was ridiculous. She turns to Mr. Bush and explains, "Mr.President, please accept my regrets... I'm sure you understand that there are some things that even a Queen cannot control."
George W. Bush, ever the gentleman, replies, "Your Majesty, please don't give the matter another thought...... You know, if you hadn't said something, I would have thought it was one of the horses."
