Bravest Warriors

If you like Adventure Time, this is a pretty awesome cartoon series by the same creator. It has the same art style and a lot of the same comedy, but without the same rules which apply to TV cartoons.

They're each about 5 minutes long each and there are only 10 episodes so far, so it should be pretty easy to keep up with if you're interested.
