Here's a little gem that I just found out about: Rainn Wilson hosting a faux book chat show, with Slash being his first guest. You can download all five episodes for free from iTunes. It's all to help promote his new film, "The Rocker". Go to Podcasts to find it.
Some of my favorite moments so far are when he gets bugged by all his movie co-stars to guest in the Office, and Rainn trying to get Slash reunited with Limp Biskit!
