When Zombies Attack

Devising a plan, you bend over and *pretend* to bite the zombie's leg. You fake chomping down on his leg, then raise your head up, making a chewing motion. "Uuaauhhuhhh," you say, telling him how good it is. He looks at you suspiciously. "Oauhh?" he says, opening his mouth. You understand what he wants you to do, he wants you to open your mouth and prove it.
