In the spirit of The Daily Show's best-selling book, America, John Hodgman's The Areas of My Expertise is an extensive compendium of eye-opening facts—except that in this case, the "facts" are almost entirely made up.
You probably know Hodgman from his work as the "resident expert" on the Daily Show or for his role as the PC in the Mac/PC commercials. But he's also a damn funny writer, and right now, you can get the audio book version of The Areas of My Expertise as as a free download at the iTunes store.
I think the offer is for a limited time only though, so hurry! To get a taste of John's humor, check out this "public service announcement" for the book.
