What's the best fan made thing you've ever saw on YouTube?

This took a while to embed... Powerpuff Girls Doujinshi fan made theme song, since it is a comic and not a show. Song in English and Japanese. You'll see what I mean when you watch it. Catchy :) *whispers* man, that comic copies a lot of characters... It has Dexter, Deedee, and even Dora (I think)!
