I spent really rather too long transcribing the BBC TV series The Atheism Tapes, the text of which you may find here, on my Cult of the Infinite Mystery of the Banana website. The cult is an effort to poke fun at religions of all flavours, especially banana flavour.
The Atheism Tapes consists of six extended interviews with some luminaries including Richard Dawkins, Steven Weinburg and Daniel Dennet. These conversations provide a pretty good grounding in various atheist arguments. It's a good series.
