Christopher Hitchens is a bottomless resource for unvarnished common sense, but he's also a damn funny writer. His often vicious wit is present in most of what he writes, but I've rarely read anything funnier from him than his three-part article for Vanity Fair, "On the Limits of Self Improvement."
The first installment was published over a year ago, but I just found it and read it this week. I wanted to share, in case you hadn't seen it. Here's a link to Part I, with the subsequent articles linked at the top. All three are funny, but nothing beats the third person "professional report and opinion" Hitchens writes about himself at the top of Part I.
There's also the painfully self-deprecating photography, shots of Hitchens smoking in the shower, showing off his stereotypical British teeth, and getting his hair cut by a world-renowned stylist. They may make you laugh. They may horrify you. But they will burn themselves onto your brain, either way.
