By now, humorist David Sedaris needs little introduction. The diminutive Greek-American expat has done for creative nonfiction in recent years what Bombshell McGee has done for face tattoos. OK … perhaps that analogy’s a bit lacking. Point is, Sedaris has revitalized a longstanding art form with a singular style that is now often replicated, seldom with any degree of success. His latest, 2008’s When You Are Engulfed in Flames, features some of the biting, sidesplitting, patently off-the-wall commentary — on Sedarian obsessions like skin parasites, bizarre social mores and peculiar neighbors — that can only come out of someone who never really intended to write for a living, but was unequivocally born to do so. Anyone who’s caught Sedaris live or heard his readings on NPR’s This American Life or Morning Edition knows the former North Carolinian’s elfin inflection and unflagging energy make his essays doubly uproarious. Oh, and keep your fingers crossed that he breaks out his Billie Holiday impression.
