This is good. Even though it's a little old. I just finished reading two of his books (given to me by an awesome New Yorker with mad book connections) and I currently listen to the Savage Lovecast (podcast) even though sometimes it grosses me out a little.
The Kid is awesome, very funny and reads really quickly.
The Commitment is a slightly slower but this is because it does a really great job investigating all aspects of making a commitment to someone you love. It's still really funny, entertaining and a great read. I have to say that it really made me change my views on marriage, which before the book went something along the lines of this shirt.
I love Dan Savage!
