Penn & Teller on Letterman.

The Penn & Teller Bulletin Board promised that the guys would do a trick that they've never performed on TV before. I was super excited. They did Teller's goldfish trick. I've heard about it before, but never seen it. It's really awesome. He basically does miser's dream into a fishbowl and then produces a whole bunch of goldfish. It was extremely well done, of course. Teller is an excellent magician.
