Customers who bought this book also bought

Interior Desecrations : Hideous Homes from the Horrible '70s by JAMES LILEKS
Scandal Proof: Do Ethics Laws Make Government Ethical by G. Calvin MacKenzie
Restoring the Lost Constitution : The Presumption of Liberty by Randy E. Barnett
Axis of Weasels by Scott Ott
Corruption and Government : Causes, Consequences, and Reform by Susan Rose-Ackerman
Warrior Politics: Why Leadership Demands a Pagan Ethos by ROBERT D. KAPLAN

Now, I'm sure Reynolds never expected, back when he started writing about the appearance of impropriety, that his book would be recommended alongside a humor book about interior decoration (or a book called "Axis of Weasels"). But, of course, Instapundit's audience is tied to Lileks' audience by the blogosphere, and that outweighs the fact that the books are about completely different subjects.
