Has Jeopardy ever featured an answer where the question was a reference to the show itself?
I don’t know, but there have been episodes of Jeopardy when the names of the categories were clearly joking references to the Saturday Night Live parody of Celebrity Jeopardy:
I couldn’t say exactly when it was, maybe late 80s, but they once used the etymology of the word ‘jeopardy’ as the clue in Final Jeopardy. All three contestants answered correctly I think (i.e. with What is jeopardy?)
I remember that happening as well. I think it could have been early 90s, but around that time anyway.
You can try looking here, although just searching on “Jeopardy” may be pretty tough. It goes back to the 1980s.
I tried searching it for “what is jeopardy” but apparently its search engine doesn’t recognize quotes meaning exact phrase…
