An absolutely hilarious video! It had me ROTFL'ng several times. And by the way the answer to three-part question is Shai-Halud (might have mis-spelt this one), a Thumper, and The Water of Life. And no, I did not look those up. No self-respecting geek, of which I consider myself one, would cheat! I found the video through the Wired article here.
