6. Mud Zombie (Season 4, Episode 8: 'Too Far Gone')
After Penny's unfortunate demise, the Governor finds a surrogate daughter in Meghan, and when he goes gallivanting off to threaten Rick's crew, she makes mud pies on the banks of a river. Except this is the zombie apocalypse, which means that a flash flood probably caught a zombie with missing teeth and no skin, and he's probably buried right in the very spot you're digging in. Let this be a lesson to you, kids.
