I used to listen to the show "Car Talk" on NPR. I have no knowledge about all things automotive, and little to no interest, but I always enjoyed listening because of the intelligence and joyful enthusiasm of the hosts. I hope these guys will take my comparison in the spirit it is offered (but what if they don't? A fine thing THAT would be!). I happen to love and be fairly knowledgeable about the Marx Brothers, but even if I weren't, I suspect I'd greatly enjoy this podcast because of its wit and fun. Add to that a truly fascinating subject truly worthy of such attention (IMO), and you've got a winner all the way around.
