David Cross is a slippery slope for me. I think that his comedy albums are absolutely brilliant, but all that good work is somewhat diluted by every interaction anyone I've ever known him to have with the service world/common people resulting in reports of him being a total douchebag. I would have never thought that anyone who was that much of a Superchunk fan would be that much of a shitbag, but I've obviously been wrong before.
Cross was on one of the late night shows recently talking about his recent month long stand of sold out London shows and did a set at Bumbershoot that is making the interweb rounds, so I mistakenly snapped this up thinking it was a new stand-up set. I Drink For A Reason is actually an audio book with Cross narrating. I would say, in theory, that this a good idea, but while the bits are decent, and it is certainly much more engaging in DC's own voice, he seems to have a DQ (douche quotient) that is off the charts. It's also very, very long, which may be either onerous or equitable depending on how you slice it. I would say that the former is the closest to the truth, but I guess you should probably decide for yourself.
Personally, I'd look for the live show.
