Assuming its the same routine he's been doing the past few years, its not so much "stand up comedy act" as "Nick Offerman telling you how you should live your life".
Its still reasonably funny, although can get a little overly crass / offensive at times, but is still probably worth seeing if you're an Offerman fan.
that's what i heard today.
tickets are too expensive and there's only single seats left for the early show, so i'm not going. kind of upsetting though.
