The Cabin in the Woods, Drew Goddard and Joss Whedon's brilliant riff on the horror genre, opens this Friday and you must see it.  It's one of the best movies of the year, and seeing it will finally allow you to stop ducking spoilers left and right.  You know and I know that once the movie opens it will be almost impossible to go on Facebook or Twitter without some jerk spoiling something, so your best option is to see this flick as soon as possible.

Today, we're proud to offer a giveaway of some pretty amazing swag for the movie.  After the jump, find out how you can win a signed poster, a t-shirt, the novelization, the official visual companion, and a collapsible bong.  That's right: we're giving away a collapsible bong (two collapsible bongs, actually; the runner up gets one too!).  And remember: The Cabin in the Woods opens this Friday.  See it.

In order to enter the contest, email thecollidermailbox@gmail.com with your name and address and say THE CABIN IN THE WOODS Giveaway in the subject line.  This giveaway will be open until April 20th and is only open to residents of the United States (sorry, no PO Boxes).  Also, only one entry per person.  Once the giveaway ends, I’ll look over the entries and randomly pick out some winners. It never hurts to mention why you think you deserve to win.  Here’s what we’ve got:
