Interviews with Randi.

Also via iTricks.com comes "The Amazing Show starring James Randi." It's a series of audio interviews with the world's favorite skeptic. He tells the story of the time he was arrested for speaking up about his skepticism as a young man and also has some really great stories about Isaac Asimov and Richard Feynman. I won't spoil the stories for you, but there's some information about Asimov than any fan (which should be everybody) will really find interesting.

(Incidentally, Asimov's Guide to the Bible is a great read. You should pick it up.)
