I'm bringing a new aspect into discussion. Sure, a shot in the head is a very efficient and cool way to eliminate a zombie, but is it really necesary? Is it really politicaly correct? I'm thinking of other alternatives to remove the threat of zombies. As one may observe in the picture below (I apologize for that, I'm not the best drawer), wich represents a zombie's bone structure if one was not clear about that, there is a certain number of weak points.
Moving is a mechanics related thing. Remove one "wheel" and the whole structure falls apart. And now let us bring the picture into discussion again.

A - the skull
Protector of Allmighty Brain.
Kill the brain, kill the zombie.
B - the jaw, or how I like to call it, the mandibulae
Used for biting.
It can be disabeled with a powerfull kick, even with a punch sometimes. Disable the biting mechanism and the zombie will not be able to bite you, wouldn't he (or wouldn't it, I'm not sure wich pronoun is more acurate in this particular situation)? Ofcourse, there's allways the danger of the zombie drooling on you and you can get infected, so beware of that.
C - the spine
Hold the hole thing together.
Brake one vertebrae and the zombie won't be able to move vary fast or even not at all. It is is recomended, though not vary valliant, to aply the vertebrae kick when the zombie is not looking.
D - that bone I don't know what it's called
Holds the spine and the legs together.
Brake it and the zombie won't be able to use its/his/hers spine nor its/his/hers legs. It's hard though to aply a perfect bone crushing kick so i wouldn't recomend this to begginers.
E - that bone on the leg, the big one
I actually don't really know what that bone does.
Aply a powerfull kick and it will break. The zombie will still be able to move but it will do it in a very slow and funny way, giveing you time to flee or to aply another deadly kick.
F - the rotulae
Keeps the big bone and the little leg bones together.
You can disable it even with your own foot, just kick it hard enough. It won't kill the zombie but it will make it/him/her slower.
G - the leg's little bones or what they are called
Tricky bones, their function being somehow related to walking.
These bones are cheecky bastards, you have to break both of them to make a zombie stop walking. I don't recomend this at all, I allways avoid this kind of kicks becouse there are a lot of things that can go wrong and we don't want things to go wrong, do we?
So remember, it's all mechanics.
