Brains.

I see the South Koreans have cloned a dog. I think I need to pay them a visit with my zombie dog, Bub. I'm gonna order up about a hundred clone zombie dogs from those guys. (If I don't eat their brains first.)

My mailman was already terrified of Bub. I can't wait to see his face when I unleash my clone zombie dog army on him! He'll think twice before ripping the cover of my Entertainment Weekly again, I'll bet.
