actually, if you think a "zombie" isnt real, you need a reality check :3

things like this have been going on for awhile

although i personally am not a believer of this hollywood zombie apocalypse

unless you take a different look at it... like instead of flesh eating dead people, id go with mindless "living" people...
which in that case the zombie apocalypse has already started!
