I listened to the audiobook version of the book narrated by Seinfeld himself. Maybe I've seen too many Seinfeld episides (HUGE FAN OF THE SHOW!) because I found the first 2/3 of the book like listening to a rerun over and over. This is not a biography - it's a compilation of all those little comedy bits that he would end every episode of Seinfeld with where he does a little stand up clip. It was ok but not great. I had hoped for some material we hadn't seen before. That said, if you haven't watched every episode of Seinfeld multiple times it will be fresh!
