Tetsu is easily my favorite member of the band, and it's not just because I'm a fellow bass player (hell, I play guitar and saxophone too), but mostly because he does the most random crap out of all of them. Take the Awake Tour performance of STAY AWAY, for instance. Tetsu pulls a banana out of his back pocket, jumps on an amp, plays slap bass with the banana, and goes on to sing the song while playing that insanely difficult bass part (sans banana, of course)
Oh, here's a video of the performance
