This book reminded me a lot of "My Brother Was an Only Child", which was written by Jack Douglas in 1959. Douglas was the head writer for Jack Paar, (predecessor of Johnny Carson). Douglas specialized in dry, deadpan essays about women, drinking, Hollywood, and middle age. It was very anti-authority and pretty groundbreaking for the 1950's.
Well, McQuinn's book isn't groundbreaking in any pushing-the-envelope sense, but it is informed by the same dry, sly, deadpan sensibility. (Example: There is a transcript of a conversation between a mom and dad and their son, where the parents explain that they are getting a divorce, and they are getting a divorce because of what a disappointment the son is. If you like that skewed take on society, then you'll like this book.)
The other thing is that this is not self-deprecating humor, where all the laughs are based on what a lame, sappy, spineless, fumbler the author is. I don't get those at all, but there are a bunch of them out there. This isn't one of them.
So, while not the most hilarious thing ever written, this book has a nice vibe, some sly lines, a few honest chuckles, and an overall engaging appeal. Worth a try, or at least a look.
