This is very clever. He/she must have watched a LOT of footage to get the perfect clips. I love the way they've used Cookie's characteristic finger in the air and face palm to convey the importance of his words, and feeling of helplessness in the context of the song. Cookie Monster never seemed more profound. I hadn't fully appreciated his ability to emote until now.
Kudos to Henson and Oz for creating a character that connects so well with people of all ages. He is my favourite SS character.
