With "The Walking Dead" returning to television this Sunday, we've all got zombies on the brain. But some superfans have gone a step further: they've got zombies on the brain, and the epidermis.

These diehard fans of "The Walking Dead" have declared their love for the show in the most permanent, public way, with portraits of the series' undead denizens inked into their very flesh. It's just a shame that all those thankless ingrate zombies probably wouldn't even pause to appreciate such fine art before sinking their teeth into it.
