I hate the ones that are WAY too long to count. Like if the category is 15-letter words, and the contestant is ruled incorrect if his response has only 14 letters.
I was going to say the same thing. I’m OK with 7-letter words, because I can sort of visualize the word as two groups of four and three letters. But those ultra-long words… I throw out a guess like “vituperativeness,” and the host goes "no, that doesn’t have sixteen letters, we were going for “vituperaciousness.” Sometimes a contestant will hesitate for a moment, and the host will make a comment like “I could see you counting the letters there.” Can anyone really count that fast?
When I play along, I never do. Either I know the answer from the clue, or I guess a word that seems long enough and hope it is correct.
The video clip in the Dogs category totally set off my dog. The little nimrod leapt off the couch and started barking furiously at the TV, then ran around the house looking for the interlopers.
Not a fan of the metal booger 
It IS a strange fashion choice. Maybe in person there’s no problem, but on television, the first impression is ‘that person has mucus/snot dripping down from their nose.’ It’s only on a second look that one sees it’s “jewelry.”
She’s a good contestant, though.
Nah, I see those in the wild every day, and they look like boogers in person too.
Every time I see a nose ring like that, I want to hook a rope up to it. 
But she’s good, even if she couldn’t get today’s (Thur) FJ, which seemed it should have been easy.
(To be fair, I didn’t get Wednesday’s. I picked the wrong small country.)
And it’s not true that Monaco borders both France and Italy, as Mayim stated. It’s entirely within France.
Maybe her brain pills hadn’t kicked in.
I HATE that commercial! “I don’t just play someone brainy on TV, I’m actually a neuroscientist!” Hawking fake BRAIN PILLS! Gah…
Watch it muted. She punctuates everything she says with emphatic head wags. When is Ken coming back?
And her phony cheerfulness, like she’s a teacher starting class with a bunch of sleepy first-graders.
I find her delay between the time an answer is given and when she declares it correct or not annoying. It’s like she’s looking at someone offstage to give her a thumbs up or down on every question.
I would think she could review the questions ahead of time (if that’s allowed), or at least arrange with the producers to work on that annoying pause. Ken doesn’t have that problem.
As host, she can, should, and almost certainly does see the game “material” in advance, so she can check on things like pronunciation. So her delays are not (or at least shouldn’t be) due to unfamiliarity with the clues.
Shaking my head at the Doolittle raid question. Ok, perhaps none of them knew the target. But when 2 of the 3 Axis capitals were eliminated and the 3rd contestant was “Uh……pass…” I threw my hands up in despair.
Yeah, and Rome and Berlin are right there, so it wouldn’t make Doolittle raids on them super remarkable.
I was yelling “there’s only one left!”
Is WWII just too old for young contestants, and people my age don’t realize? Or should they know these?
Yeah, that one stood out to me as well. Most of the popular history and rememberances of WWII are about the fighting in Europe, and Germany specifically. Maybe the contestants had grandfathers who fought in Europe, and so Japan just didn’t enter their minds.
