There are several rules to surviving the Zombie Apocalypse. First and foremost though one should take a page from the British during the WW II and 'Keep Calm'!

Made from 100% cotton, the Walking Dead Keep Calm And... T-Shirt will spell out the rules to surviving a horde of rather bitey individuals and tyrannical dictators of suburbia. Those neighborhood watch guys can get awfully carried away.
