Across the Universe - I Want You (She's So Heavy)
I mean, DAMN. This is one of the most amazing musical "dance" numbers I've ever seen. Gives a whole new dimension to the song. The scene is Max responding to his Vietnam-era draft notice. Oh, and the stuff he eats at the beginning is cotton--someone told him that if he ate cotton balls it would make a shadow on his lung and they wouldn't draft him, heh.
