Air Force One arrives at Heathrow Airport, and President Obama strides to a warm and dignified reception from the Queen. They are driven in a 1934 Bentley to the edge of central London, where they change to a magnificent 17th century carriage hitched to six white horses. They continue on towards Buckingham Palace waving to the thousands of cheering Britons. All is going well.
Suddenly the right rear horse lets fly with the most horrendous, earth shattering fart. The smell is awful. The fart shakes the coach, but the two dignitaries of State do their best to ignore the incident.
The Queen turns to President Obama,
"Mr. President please accept my regrets... I am sure you understand there are some things that even a Queen cannot control."
President Obama, trying to be "Presidential," replied:
"Your Majesty, do not give the matter another thought; until you mentioned it, I thought it was one of the horses."
