What annoys me are people who dance their way down to contestants' row on TPiR. It's okay to be excited but it feels like dancing down just wastes time. 

I feel the same way about people who high-five everyone on their way down to the stage. I also have a dislike for really "over-the-top" contestants and really long sob stories. It's why I stopped watching DOND and The Wall.

I enjoy seeing excitable contestants on shows that are normally staid, like Jeopardy. I also like seeing calmer contestants on shows that are usually high-energy, like Price or LMAD.

Before this goes too far into old men grumbling at clouds, I think today's audiences have a wider spectrum of hyperactivity. In previous generations, a good chunk of your hyperactivity would come from people who would've rarely have left their town, let alone fly on a plane and go out of state to a place they've never really seen before and taking in everything is A Lot but now they're on a game show and winning a prize worth a lot of money. You still have similar situations now, but more of the audience is a bit more savvy both to the concept of California and being on a game show; their hyperactivity could be more along the lines of people who get hyped for sporting events or concerts, which is a different type of hyperactivity than the homebody who may as well have been transported to another planet.

(I'm also thinking coordinators are a little less likely to cast people who would be truly out of their depth, but that's a different conversation.)

One more relevant anecdote: I do Name That Tune at conventions, my version being three qualifiers via audience participation and the winners of each play off in the final, and each round has further audience participation whenever contestants deadball a tune. In the first qualifier I get someone who's more excitable than normal--she has a way too-early buzz-in and doesn't do much after that, but nothing else too noteworthy and the game goes on as normal. During the final, however, this person starts going wild whenever one specific finalist named Addison (possibly from the excitable lady's heat?) gets a tune right. Addison ends up running away with the game, so our excitable lady has plenty of opportunities to be excited, and I find each successive instance to be increasingly funny. I make a couple jokes and try other ways to not corpse as I try to play the final round out. About three tunes from the end there's a deadball and our excitable lady gets a chance to jump in; she gets it and I reply with the most excited "YES!" I might have ever exclaimed. Once the game is over and credits roll, I go over to personally thank this lady for coming because she was delightful and made the entire show for me.

tl;dr I'm not sure how I feel about watching hyperactive contestants, but I absolutely love hosting hyperactive contestants.

I don’t mind hyperactive, and those types existed back in the day. I mind when they’re over-the-top and look like aspiring actors, or the producers coach the contestants to be on 11 at all times. Not everything has to be tailor-made for YouTube content (looking at you, GSN).
