Movies and their trailers have always been symbiotic. These days, there's a trailer to preview any upcoming film—and if there isn't one, well, good luck at the box office. A new trend, though, is *drumroll* trailers for books!

Last week, we showed you "Wizard of Ass," the book trailer (the latest dubious trend in book promotion!) for Fight Club author Chuck Palahniuk's new book, Snuff. It was a parody of bad 70s porn, because his book is about an aging porn star ending her career with a bang—a gangbang! Now we've discovered that the book, out today, has two more trailers, "The Twilight Bone" and "Chitty Chitty Gang Bang." OK, Chuck: one jokey porn short film to promote your book is clever, whatever. But three? Click to judge the camera angles of the SFW "Twilight Bone" for yourself.

Fight Club author Chuck Palahniuk, coiner of the term "suicide girls" and writer of stark raving mad fiction (people have fainted during his readings), has a new book, Snuff. As it the trend right now, he also has a book trailer. As Fleshbot pointed out, it's a porn parody, as the book concerns a gangbang. Is it SFW? Sort of... there' no nudity, but your boss will assume you're watching bad 70s porn. (Here's the test of a good book trailer: after watching it, are you able to figure out what the hell the book is about? Well...)
