This is such a waste of time.
This is a small clip of the most amazing Japan TV-show ever. It's an educational show, mostly about math I guess. Here comes the nice part. The start and end of every episode has a Rube Goldberg machine, afterwards showing a Japanese text "Pitagora Suicci", meaning Pythagorean Switch, hence the name.
Watch out, though: the jingle at the end is annoying.

GO. THERE. NOW.
(PS: Honda also had a commercial based on this.
