Alex Trebek: Obama did a 'very subtle audition' for my 'Jeopardy' job

Longtime "Jeopardy" host Alex Trebek introduced Obama, who in a video asked a question of the bee's final contestants and also pointed out a presidential mistake. 

"Now my answer," Obama said in the prerecorded video. "In March, I met with leaders from more than 50 countries at the Nuclear Security Summit. … This Asian capital, located on the Han River, hosted the meeting."

Trebek pointed out that the president used the "Jeopardy" format, giving the answer and waiting for the contestants to guess the question.

“Is it just my imagination, or did the president of the United States just do a very subtle audition for a possible future job as the host of a very popular quiz show?” Trebek said.

Trebek had some nice words for the president, calling him “very intelligent and “a lot younger than I am.” But Trebek said the "Jeopardy" job wasn't open. “I’m not ready to move on just yet.”

Fifty-four students took part in the Geography Bee, and the final round airs Thursday night on National Geographic Channel and Nat Geo Wild.

The correct response to the president's question — Seoul, South Korea — did not need to be phrased in the form of a question.
