As to Prince of Tennis... I finished Season 1 (in a week, atashi no bigi ni yoi na!) and... I gave up and skipped Season 2 for the time being so that I can watch Hyoutei. I'll go back and watch it afterwards, but I simply couldn't wait anymore. XD;;;
Uhh. It's a lot like the musical, LOL. It's kind of funny, seeing that I've watched the musical so many times, I like. Know the script of the episodes. It's really amusing. Still, I'm only episode 56 and it's SO AMAZING. Atobe had overshadowed my love for Dirty Pair a little bit, but OH GOD I LOVE THEM SO MUCH. I always feel a little bad for Gakuto, because it's so apparent that Oshitari is a better player than him... but Oshitari loves him anyway, right? XD;;;
I also developed this theory about Gakuto, because, really. There is no reason to want to play tennis while flipping in the air. It can't possibly make it easier. So I think Gakuto's inner ear must be kind of out of whack, such that he has better perception while upside down than he does right side up. XD;;; Because that's the only way I can make it make sense to me. At all. XD;;; Even if the Moon Sault is fucking awesome. WTF @ playing tennis midair.
And yes, Gakuto totally uses his Acrobatic Play in bed. XD;;;
Oh, and it made my day that Oshitari and Gakuto actually enter the court saying "Katsu no wa Hyoutei, Makeru no Seigaku." XD;;;
[EDIT] Okay, seriously, it's disturbing that the lyrics for Sannin no Doubles come directly from the anime. o____O;;;; They're like. Talking the lines. There's like. 2 differences, I swear to god. Like. I'm singing along in my head. It's fucking weird that they could take the lines word for word from the anime and make them into a song.
... Also I've been watching TeniMyu way too much so I know a lot of the lyrics lolz.
