"Oh the cleverness of me!" -Peter Pan
I just find him to have such a youthful, energetic, fun-filling quality about him even though his position is still and there just isn't much action. I can just see him jumping around pulling all of the painter's items out in the studio asking "Oooh, what is this peculiar thing, sir? OH! And look over there! Can I play with that? Or, excuse me-MAY i play with that?" in a sarcastic and scheming tone. He looks like he could take off, like he's Peter Pan forced to dress up and stand still, which is not who he is.
