It's not really a music video -- even though it comes from a music album -- and for the most it's not really animated in the sense that it conveys motion.
Rather, this one-minute long spoken-word video of The Thin King's "They" from Me3 is how Shel Silverstein would be communicating today if he were still alive. Perhaps it's even a long-hidden outtake -- Jason Kleinberg's drawing looking not a little bit like Shel's. I think Shel would approve.
