So ... exactly what happens when a Zombie is bitten by a Vampire, or vice-versa? (never mind werewolves, everybody knows there's no such thing as those).
but HOW MUCH gubment $$$$$$$$$$$$$$ did those universities get to study the looming zombie attacks and how to prep for them?
It doesn't really matter how ridiculous the documentary was (though entertaining);
It doesn't matter zombies don't exist;
THEY GOT MONEY, OUR MONEY!!!!!!!!!!!!!!!!
I think that's a very catchy, mainstream approach to get people prepared. On that page that you listed, here is what they said:
"If you are generally well equipped to deal with a zombie apocalypse you will be prepared for a hurricane, pandemic, earthquake, or terrorist attack. So please log on, get a kit, make a plan, and be prepared!"
