Picture a zombie version of your head sitting on the fireplace mantle. Cool, right? Well, at this year's San Diego Comic-Con, one lucky attendee will get just that thanks to the Where's Merle Twitter contest. All it takes is four easy steps to participate in the contest.

1. Visit The Walking Dead Booth at Comic-Con.
2. Take your photo in AMC's replica of the rooftop scene from Season 1.
3. Follow @WalkingDead_AMC on Twitter.
4. Post your photo with hash tag #WheresMerle.

Do the above and you'll be automatically qualified to compete for a round-trip for two to L.A. where none other than Greg Nicotero and KNB EFX Group will craft your zombie head lookalike. And even if you don't win, you'll still have a pretty great photo as a souvenir.
