When the now-famous Youtube video for this song was released, I was absolutely hooked. It's an entire Rube Goldberg machine dedicated to playing one and only one song, but to play it oh-so-well. Every hit of percussion, knock on the xylophone, strum on the guitar, is produced by a marble. You can hear the marbles shuffling away in the background, giving this track that feeling of a mad scientist achieving something wacky, great and wonderful.
