It's Adventure Time!
Watch this cartoon by Pen Ward. Besides the fact that it's totally absurd and ridiculous in the best way possible, I love this because it brings me back into my eight year old head. With exclamations like "Algebraic!" and "Mathematical!", it's clearly written for those of us that haven't strayed too far into the land of boring grown-ups to forget what it was like to make up stuff on the spot and have your friends totally understand you. With Rainicorns, Elementos, Abraham Lincoln and a wizard that is such a patoot, you have to watch it to believe that somewhere in the galaxy, this world must exist. Confused already? I don't blame you. This cartoon is worth watching over to get it, but even more because it's just that awesome.
