Jon Cozart (AKA Paint)
He is the best! He does all the "X in 99 seconds" videos...actually I think Miranda posted a version of the Harry Potter one set to the trailers a while back. But now he is most well known for After Ever After, where he says "why Disney tales all end in lies"
And he did the coolest version of the Cup Song ever.
