In the late 90s there was a Mexican version of Jeopardy!, and for some reason they decided to add dancing girls to it: https://youtu.be/P0DUhx0avLw?si=9-eF21sIIsSz68eF
I did not expect them to dance for quite so long at the beginning there...
(Note: I am watching a different episode than the one I linked)
The Japanese version of Jeopardy! is basically exactly as I expected (though I didn't think they would have more than 3 contestants)
They seem a little looser with the rules, too. At one point there is a question about Batman where one contestant answers, "Poison Ivy" and the host is like, "No we want the actress" and the guy says, "Uma Thurman" and gets it right.
Later on no one buzzes in on one of the questions and after the host is ready to move on one guy tries to hit the buzzer and the host is like, "Oh hey you want to answer?" And the guy gives a response.
