Radagast would totally think warg bellies are fluffy.

So when I was a kid I liked this comic strip Wizard of Id, namely because there was a wizard in it (yeah that all goes back quite a ways). I don't have it anymore, but I distinctly remember clipping a particular installment of the comic out of the paper and saving it:

King: "What are all those white spots on your robe?"
Wizard: "Those are all mystic symbols. ... Except this one."
King: "And what's that one?"
Wizard: "Bird dookie!"

So that explains that. X)
