Oz on Jeopardy

I was rather preoccupied with the Aquaman reference earlier in the show, so it took Eric to point out the Oz reference which came on the very last clue of Double Jeopardy, the $400 clue in the "Not The Dreaded Spelling Category", in which all the questions were only two letters long.

The question for this one was, of course, "What is O-Z?" (They had to spell it, not say it). The first contestant to ring in got it right (by coincidence, he also was the contestant who got the Aquaman question correct).
