WOW.
This is the first animation I've seen maybe in my entire life that has led me to try and emulate what I saw. I am literally, as I one-handedly type this, trying to touch my elbow to my chin. It truly is anatomically impossible.. and so for your great animation skills, hilariously relevant music, and factual depiction of biological science.. you get 10/10 and 5/5 from me. Sweet job. Also, thanks for subtitles!
