Good Neighbors by far, my favorite character is Squidward, after all. And I certainly don't like to see that kind of abuse inflicted on the poor guy.
Like what The Cartoon said, I also am part of his minority group, meaning I actually loved SpongeHenge too. At least I know I don't hate or dislike the episode, so maybe my opinion on it could also be "meh." (Meaning along the same lines of that I think SpongeHenge was average.)
