"I'm 12!"
"I'm 28!"
That was the most hyperactively enjoyable seven minutes of animated goodness I've seen in a while. And, while thinking about the "over-quoted movies" thread, I think this little short has more quotable stuff in it than Napoleon Dynamite or what-have-you.
P.S. I also find it funny that one of the recommended links after watching that is a video for Deep Purple's "Child in Time," a song I was listening to while doing dishes this weekend. It all comes full circle. And totally randomly, at that!
