That was a good movie. Though, I wasn't too surprised that it was good because, well, it's Galifianakis.
I had the pleasure of seeing Zach do standup twice... once in DC, and once in NYC at a very small blackbox theatre. I agree that he definitely needs to do more standup. I think after the Downey movie comes out, he should tour. He'd sell out every show.
