Would anyone believe me if I said that when I saw Gryllidae family I thought that it was referring to a character name from Harry Potter? I immediately recognized that it looked similar to Gryffindor and guessed that it was going to be the name of some minor character from the books. Luckily cricket also came immediately to mind as a world sport that could also be a person's first name, and I instantly convinced myself that Cricket Gryllidae was a female character created by J.K. Rowling. If I had been appearing on this episode of Jeopardy!, I would be glad that we don't have to "show our work" in Final Jeopardy!
As to the wagers, yeah, very curious. It actually appeared as if both Alex and Ken made a math error, as it would make some sort of sense that each was trying to get to $16,601, but Ken was $200 too high while Alex was $1,000 low. Not that $16,601 was really a sensible score for either to shoot for, but there is at least plenty of precedent for 2nd and 3rd place players aiming to top the leader's pre-FJ score by $1.
I caught Justin's mistake in saying the Wayans Brothers, rather than the Wayans family, so I wasn't surprised that they negged him before the FJ clue reveal. Interesting that the score correction likely didn't cost him any money, as I had assumed that he would bet enough to reach $24,401 before the correction, and he ended up at that same score after it, not like yesterday where he may have lost about $10,000 by (in my opinion) being unfairly negged on his late Daily Double response.
What would have been interesting had the correction not occurred, is that his likely FJ wager would have been $6,201, and if he responded incorrectly but still won, his 4-day total would have been $88,799, leaving him in 12th place in the TOC standings, a mere $5 behind Buddy Wright.
