At Heathrow Airport, a 300-foot red carpet stretches out to Air Force One and Mr. Bush strides to a warm but dignified hand shake from Queen Elizabeth.

They ride in a silver 1934 Bentley Limousine to the edge of central London where they then board an open 17th century coach pulled by six magnificent white matching horses. They ride toward Buckingham Palace, each looking sideways and waving to the thousands of cheering Britons.

So far everything is going well. Suddenly the right rear horse lets fly with the most horrendous, earth-rending, eye-smarting blast of flatulence ever heard in the British Empire and so powerful that it shakes the coach.

Uncomfortable, but under control, the two Dignitaries of State do their best to ignore the incident. But, embarrassed, the Queen decides it's impossible to ignore it. "Mr. President, please accept my regrets I'm sure you understand that there are some things that not even a Queen can control."

Ever the Texas gentleman, the President 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!"
