Let me ask you this: if you were standing alone in a dark alley and some PCP-freak charged at you, would you even be able to pull out a sharpened wooden stick in time, nevermind get it stuck deep into his heart?
Here’s a science experiment you can do at home!
Go cut the last foot or so off of your kitchen mop. Sharpen it with a knife until its got a sharp point. Then, go to your local supermarket and buy a rack of ribs. Bring them home, and try to jam the wooden stake through the ribs.
You can’t do it, can you?
Now imagine trying to get through those ribs when they’re coming at you at a sprint, and the dude attached to those ribs is slashing at you with his hands, and trying to chew your face off. It’s just not going to happen. And if the guy is wearing even a simple denim jacket, the spike probably won’t even pierce that.
No, you can’t kill a vampire with a wooden stake simply because vampires, like humans, aren’t going to lay down naked and give you three lucky shots at their heart! I hope this lays this ridiculous claim to rest.
