Popular culture is complicated.

On several occasions, Celebrity Jeopardy! sketches have been referenced during actual episodes of Jeopardy!

In the May 19, 1999 Celebrity Jeopardy! episode, the Jeopardy! round featured the category “‘S’ Words”, and the Double Jeopardy! round featured “Swords” in the same column (Connery misread “‘S’ words” as “Swords”).

During the September 5, 2001 episode, the Double Jeopardy! categories were “Sean Connery”, “Surprise Me, Trebek!”, “Therapists” (misread by Connery as “The Rapists”), “Things You Shouldn’t Put in Your Mouth”, “The Number After 2”, and “Rhymes With ‘Dog'”.

The June 27, 2006 episode featured the category “Japan-U.S. Relations”, which had been misread by Connery as “Jap Anus Relations”.

In the 2006 Celebrity Jeopardy! tournament, categories included “Surprise Me, Trebek!” and “Answers That Start With ‘Feb'”.

On the November 23, 2009 episode, the categories in the Jeopardy! round were inspired by Celebrity Jeopardy!, including “SNL Celebrity Jeopardy!”, “States That End In Hampshire”, “What Color Is Green?”, “Current Black Presidents”, “Sounds That Kitties Make”, and “Twinkle Twinkle Little Word That Rhymes with Star”.
