Andy’s Pregame Thoughts:
Despite what some of the A.I. hallucinations might have told you last night, Harrison Whitaker is still your Jeopardy! champion, having won his 8th game after his nearest opponent bet too much in Final Jeopardy. (If you’re a prospective contestant, I would strongly suggest focusing on wagering until you can do it under any conceivable circumstance—because that will be the pressure you feel on the Alex Trebek Stage.) Harrison gets to the end of the tape day, going for victory #9 against Sarah Wylie of Boynton Beach, Florida and Jamie Kohlmeier of Sarnia, Ontario.

Correct response: Who is Nikola Tesla?
More information about Final Jeopardy:
(The following write-up is original content and is copyright 2025 The Jeopardy! Fan. It may not be copied without linked attribution back to this page.)
As a youngster growing up in the Balkans, Nikola Tesla had a favorite cat, named Macak. And on a cold (and dry) winter night in the Balkans, the air was ripe for large amounts of static electricity—and, as one might guess—Tesla was shocked by the cat when petting it. Tesla’s father, normally able to explain the world to his son, was unable to explain the electricity, leading to Tesla’s lifelong obsession with electricity. As he put it, “Is nature a gigantic cat? If so, who strokes its back?… Day after day I have asked myself, what is electricity?”
I think that this clue, as it’s showing up as “Clue of the Day”, needs one more word (Balkan) to prevent the incredibly obvious negbait (whose name I won’t say here, due to the stories about that other scientist’s predilections that have surfaced over the past few years.) I’d be impressed if this clue played any better than 1-for-3.
