How to Kill a Zombie

Just came across this article from 2004 on how to kill a zombie. (Can you really kill the undead?). It lists decapitation, bludgeoning, burning and exploding. Decapitation and bludgeoning seem the surest way of the four. (I don't know why it doesn't mention shooting them in the head...). Burning seems more dangerous than helpful. Imagine a huge torch lurching around, touching off fires here and there. Explosives probably aren't as useful either, unless you use one of these.
