Is Mark Leyner funny? Yup, and clever too, and "My Cousin, My Gasteroenterologist" is full of good jokes. The problem, then, is that they're buried under so much junk and pseudo-transgressive "genre-busting" that you'd never know they were there unless you look really closely, and having to put that much effort into finding humor kind of negates its value as humor. Which is a shame, because Leyner's obviously smart and has something to say about something (His short piece - not in this collection - about the Death of Postmodernism is fall-out-of-your-chair funny). Kinda just wish he'd settle down and stop congratulating himself and write a real book, one of these days. This one's an amusing diversion, and he's obviously talented, but it's not much else. It'd be sad if Leyner wasn't satisfied with just a smirk.
