I like Frank Cifaldi, and I like Penn Jillette, so by rights I think I have to link to this article by Frank about Penn. Specifically, it's about Penn and Teller's Smoke and Mirrors, an unreleased (but finished!) Sega CD game starring the magical libertarian duo.

The best part of the game, no question, is Desert Bus.
More on the game, and why Desert Bus was developed (hint: Janet Reno), at the link. You can even listen to Jillette's podcast where he discusses the game. Apparently they're okay with its free distribution over the Internets, and you can download it here.
