One chapter details Mr. Sedaris 's fascination with dead bodies ( as a boy , he says , he used to keep digging up the bodies of dead pets , after he 'd buried them ) and features a " CSI " -like trip to a medical examiner 's office , during which Mr. Sedaris watches a pathologist collect maggots from a victim 's spinal column and learns that " if you jump from a tall building and land on your back , your eyes will pop out of your head and hang by bloody cables .
