I don't think that zombies are all that concerned with proper identification or work habits but you may still want to get the 18 inch long Zombies All-Over Print Lanyard w/Head Charm just in case. Hey, maybe that's why the zombies are always running around and eating people...they just don't know who they are because their ID isn't on display! Nobody ever thought of that, right? Who needs some regular lanyard when you can get the Zombies All-Over Print Lanyard with a soft PVC Head Charm! Braaaaaaains.
