There's a lot to like about the episode, but I was especially amused by how self-aware and self-satirizing the clip show was regarding the concept of clip shows themselves- especially the various fourth-wall breaks regarding the concept and the inclusion of clips from episodes that don't exist. (And I'm surprised they were able to find a sensible way to use one of the non-sequiturs from one of those said clips!)
