Adventure Time (S01E20)

Episode #020
'Freak City'
Season 1, Episode 20

Finn gives a beggar a cube of sugar, when it is revealed that it wasn't actually a beggar: it was the Magic Man. To "repay" Finn for his charity, he transforms his body into a gigantic foot. Unable to fight bad guys and function as he used to, Finn winds up getting thrown under a bridge by some townsfolk for being a freak, where there are other people transformed into body parts like him.

The first appearance of the magnificently annoying Magic Man, this episode is hilarious and doesn't even care if it isn't teaching a lesson (despite the set-up implying there's one to be found). Magic Man is one of those characters that you can't help but to hate, but his presence almost always makes an episode better. Sometimes episodes feel like they've missed an opportunity by not having any kind of message or moral, but not this one. The lack of an actual point makes it somehow all the more hilarious. Jake enjoying that Finn is now a foot is also a funny sidenote, and several of the jokes thrown in there are the appropriate amount of stupid to just add to it all. This isn't an adventurous or exciting episods, but it's a funny one, and sometimes that's all you need.
