Bonus video, because it’s Friday: Penn and Teller do the old cups trick. Except they use transparent cups and finish off with a potato. Thanks to Penn Fans for that one (is there a Teller Fans site?).
And speaking of Penn and Teller, don’t miss the riveting mini-game Desert Bus from Penn and Teller’s never-released mid-nineties PC game, Penn & Teller’s Smoke and Mirrors. You can also hear Penn Jillette discuss this masterpiece (MP3).
