So....quick question, what movie is this from? I obviously need to watch this as soon as possible, because honestly the greatest mystery in my life has now approached me....what in God's name is the buildup to that scene? What compels a man to wear such an outfit, put on an awesome headpiece, and then dance like that in front of a crowd? I must know!
