A whole episode with fanservice as i expected but...it's still not good as a real comedy somehow, though there's a lot of hilarious scenes.
Well, the strong point of higurashi's not the comedy but i still liked the episode anyways
Spoiler for the episode:
Though it's not really perfect but they really had good ideas when making it. Having Chie-sensei used "Black Keys" is one of main reasons made me laughing so hard
(if you read Tsukihime, a visual novel by Type-moon, you'd understand)
