I saw Ant Farm by Simon Rich (ISBN 9781400065882) on the "new non-fiction" shelf at the library the other day. A blurb on the back cover by Jon Stewart (whom I find very funny) says "Hilarious. Open this book anywhere and you will laugh." That's a pretty tall order for a comedy book, so I tried in on three different pages and did laugh pretty heartily on each. After checking it out and reading it cover-to-cover (it's not that long), I believe that Stewart's bet is a good one. Well worth reading.
One of the best pieces in the book was recently in the New Yorker, and an interview with the young author is here.
