Looking Like A Nobody

Ok I got this thought from the nomnomnom topic thing, what if you could blend in with zombies but if you talked and seemed human they would eat you. Now I mean like all you had to do was act like a zombie "kinda like shaun of the dead just don't mess up like Ed." would you risk going outside a bit more if this was all you had to do? And also what if you had to cover yourself in the zombies blood and guts etc.. "got that thought from the walking dead show."
