So totally fake. It's just him messing up a rubik's cube with his feet except backwards. You can see because his friend has a weird looking limp (he was walking backwards) and there's a point where the cube "jumps" up to the bottom of his foot. Good editing job, though, taking the sound out and putting in new sounds not reversed and having his friend walk backwards WOULD have been good if he didn't do such a crap job at it.
