This is a pretty good book by writer Saul Austerlitz. Each chapter is about an episode of a sitcom and also that sitcom itself. I have not finished the book yet but I am enjoying it. I will probably finish it soon.
I liked the chapter on Community. It was one of the first chapters I read. The chapter covers the episode Modern Warfare.
I liked the chapter on Seinfield more than I expected to like it. Which is interesting because I cannot remember watching an episode of Seinfeld in the last two years.
How I Met Your Mother did not get a chapter, which seems odd, It was a bigger hit than Community. Also it updates Friends to an extent.
