It's not a book.
Just a jokes' compilation grouped by decades.
If you find this in an airport store, take it. It will be a fun fat magazine type printed publication.
I really enjoyed it.
Seinfeld is extremely funny, if you like his comedy, this is a must read. I must say he's very talented and you probably won't feel disappointed by the compilation. But this won't be anything remarkable in your reading life.
I haven't read a book in years. This is what I choose to come back to my former favorite hobby: "It is what it is"
