This Green Bay Packers quarterback tested his know-how against a famous NASA astronaut and a TV personality.

Who is Aaron Rodgers?

Yes, Rodgers will be on an upcoming episode of the show shot this week, according to the Twitter account of Kevin O'Leary. O'Leary, an investor and financial expert better known as a panelist on ABC's "Shark Tank," posted a selfie of himself with Rodgers, NASA astronaut Mark Kelly and Alex Trebek.

According to the caption, the show will air May 12.

Celebrity Jeopardy is a long-running special feature of the trivia show, one made even more famous by a successful run of skits put on by Saturday Night Live, in which Trebek -- played by Will Ferrell -- is insulted and hassled by self-centered celebrities who know almost nothing in terms of useful information.

Rodgers' appearance on the show provides a perfect time to revisit the best athlete moment in the history of Celebrity Jeopardy: Kareem Abdul-Jabbar answered a question with his own name -- and got it wrong:

Tough one, Kareem. You looked like a real Turd Ferguson.
