Joe Klein's (I hate to plug the dude) New York Times review of the biography Gonzo: The Life of Huter S. Thompson by Jann S. Wenner and Corey Seymour has this little rejection tidbit for you today. Apparently Thompson donated a rejection letter to the Rolling Stone to ward off imitators. It opened as follows: “You worthless, acid-sucking piece of illiterate shit. Don’t ever send this kind of brain-damaged swill in here again.”
Now that's what I call straight and to the point. I'd kill myself too.
