If you have never seen an episode of Adventure Time, stop whatever it is you're doing and go do so. I don't care how you have to get a hold of some. It's by far the most original, silly, awesome, quality cartoon show out there right now.
This is probably my favorite 'limited' character (he's only appeared in a couple episodes). His name is Magic Man, and (spoiler alert) he's a jerk. I love him for it, though.
To reiterate, GO WATCH ADVENTURE TIME. You will not regret it.
