So.. near as I can tell, this "dance" is literally just swinging your arms from side to side, and then taking two steps in a row... Is that about right?
My favorite part of that clip was always that at the very end, after doing his little jump and posing, he almost falls over but manages to steady himself, and instead of doing another take they just went "fuck it" and left that in.
Who would have thought decades later so many kids would be so out of shape that this is pretty much all they could do without getting tired? NINTENDO IS PROPHETIC!
