You no longer have to read about Prince Philip’s propensity to put his Lobb-shod foot in his mouth.  You can actually see and hear him in action at his first meeting yesterday morning with what the British press is now calling “the coolest couple on earth.”
On the principle that we’re dealing with four people separated by a common language, subtitles are provided below.

 

EIIR:  Where did you have breakfast?

POTUS: I had breakfast with the Prime Minister.  I had meetings with the Chinese, the Russians, and David Cameron, and I’m proud to say I did not nod in any of the meetings.

PRINCE PHILIP: Can you tell the difference between them?

POTUS: It’s all a blur.
