You'd THINK a Lord of the Rings parody would be played out by now. For the most part, you'd be right. But AD pulled it off so well, that it's hard to fault it. Everything with Roger's Gollum was just perfect and I absolutely loved the ending with him biting Stan's finger off. And there was really nothing that could beat Roger falling into the faux torch. Just fantastic.
Side plot was...interesting. I can appreciate them trying to establish Reggie the CIA Koala, but his interaction with Haley just seemed...odd. Though his reaction to Haley flashing him was great. "If those were guns, Reggie'd be dead."
I'm gonna let you finish, but my pink shirt demands your attention!
The bit at the end where Pierce was bequeathing stuff to the group was some really nice character work. All of the gifts reference things that happened in earlier episodes and make sense given the characters relationships - even Abed, who got nothing.
