Fifty years ago this week, NBC debuted a daytime quiz show in which contestants were presented answers and challenged to pose the corresponding question.

Thanks to the work of devoted fans, virtually every answer from Alex Trebek’s 30-year reign on Jeopardy! is recorded at j-archive.com. These 256,000 clues amount to one weird and revealing record of our time.

You can see for yourself below. Just put a topic in the search box below, and see how often it’s been used on Jeopardy!–and how it compares to other answer. Hint: Justin Bieber is now beating Einstein.

To search different Jeopardy! clues, separate them by commas and press search. “Cats, dogs” will show how often cats have appeared on the show versus dogs.
