DP [and anyone else who likes good 'casting], if you haven't heard Hardwick nerd out with Wesley Crusher, do so now. Not so much for the funny, though there were a number of wisecracks, but for the stories and the history. In case you were unaware [though surely you can't be] Chris and Wil were childhood friends and roommates in their 20s. Never was a Trekkie, so I barely know anything about Wil Wheaton, but you can feel the affection between the two.
Probably the best podcast I've heard in a while, from anyone, and I'm not always the biggest Nerdist fan [especially since he's gone guestless once a week].
