What's The Cause?

There are many "claimed" causes of how a zombie comes to be such as radiation, psychological manipulation, drug induced, necromancy magic, divine intervention, paranormal activity, incredible acting, evolution, alternate dimensional side-effects, aliens, viruses, mass schizophrenia, they were born that way, and others of the sort, but the most popular is the idea that mankind brought this upon themselves by manufacturing their own custom virus that has ironical been stated that it was made to help humanity *laugh*

But how much do you really know about this so called "virus"? I suggest that you watch this and educate yourselves. The more you know, the more you can show off to potential sweethearts and your boss :)
