I love the way you animated the expressions, especially when they were laughing at the end. Also, the "Nine tails IN YA FACE!" at 0:37 part, too.
Be honest this animated take on the scene is way funnier than the original GG video it came from, but that's beyond the point, I suppose.
All-in-all, you did a great job here! (wish I could animate like this, or really, wish I could animate, PERIOD...=P)
