The book is absolutely brilliant. The show's been a bit hit-or-miss lately, as some of the guests are really lame. But it's still one of the best shows on TV.
I love Lewis Black -- he looks and talks just like my late grandfather.
As for Dennis Miller's show, it's been improving. Just skip the opening monologue -- he REALLY needs to hire new writers for that. (Although last night's was actually pretty funny.) But the Varsity Panel discussions and most of the guests are good.
