It was a round table pre-interview moment seen around the world. Former President Barack Obama and Prince Harry were warming up before a BBC Radio program when their back-and-forth got a little silly.

BBC News writes that Prince Harry warns President Obama will get "the face" if he pauses too long between answers -- in apparent joke about how most interview segments are produced for BBC.

Mr. Obama then asks Prince Harry to see the face and after seeing what happens, Mr. Obama said, "I don't want to see that face."

"I'll interview you if you want," Mr. Obama asks. Prince Harry chuckled: "No, no, let's keep it this way ... I much prefer that."

According to BBC News, the interview was recorded at this year's Invictus Games in Canada and will broadcast for Prince Harry's guest edition of the BBC Radio 4's Today program on Dec. 27.
