Retrospective-Avatar: the Airbender Book 1, Chapter 5-The King of Omashu
Damn I love this episode. It's really funny, it's the first episode with the Cabbage Merchant or the Earth Kingdom for that matter (Kyoshi Island doesn't count), the King is a riot, the fight scenes rock, and it's just an all-around good episode. It's so good I think that the movie would have been slightly less awful if they'd chosen to adapt this episode rather than the one the follows it. But that's a story for another day.
