Hey, creepy readers. You know what this site needs more photos of? Jon Hamm. YOU! As usual, EW will be running a gallery of our readers’ best pop culture Halloween costumes. (Witness: 2009’s, 2008’s. Ooh, maybe you should go as Harrison Ford in Witness.) To achieve eternal fame — and the chance to win a DVD set of spooky movies (Nightmare on Elm Street, The Exorcist Extended Director’s Cut, Pan’s Labyrinth Special Edition, The Shining, Texas Chainsaw Massacre: The Collector’s Edition, courtesy of Warner Home Video) — upload your pic to Entertainment Weekly’s Facebook page. Just “attach” the photo to our wall and your image will appear in the Just Fans section. (You’ll have to “like” us first. Time to make this co-dependent relationship official.) Make sure to tell us your name, location, and what you’re supposed to be (even if you think it’s obvious … it’s not always obvious).

We’ll be posting a reminder later in the month, but start rummaging through the dusty files of your hard drive now. No thumbnails, please. Show some class.
