Nothing worse than the "Shovel Zombie" towards the end of "Day". In defending himself, one of the characters sticks a shovel in a zombies mouth and pops the top of his head clean off. As the characters run away, you can see the top part of the zombies head laying upside down, it's eyes still moving around.
Man, an existance of just laying upsidedown in a dark cave till your brain rots. I felt sorry for that zombie.
