From My Cousin, My Gastroenterologist, by Mark Leyner. Which explains why I am SO excited about this.
EDIT: Well, I say it explains it. Perhaps it doesn’t. Let’s say instead that Leyner’s prose veers from the perceptive and biting to the bizarre, and that ingesting his previous books has been like injecting madness directly into the eyeballs. So I consider this something of an event. In which, thank God, I’m not alone.
