Mommy.. Where do the walking dead come from??

[Doc Daneeka]

Pet Sematary - Dead come back with memories, but no soul or different soul... I think, it sounds right!

When the world is ruled by violence
and the soul of mankind fades
the children's poath shall be darkened
by the shadows of... ZOMBIES!

[DodgingGrunge]

When the world is ruled by violence
and the soul of mankind fades
the children's poath shall be darkened
by the shadows of... ZOMBIES!

Death, death, death comes sweeping down
Filthy death the leering clown
Death on wings, death by surprise
Failing evil from worldly eyes
Death that spawns as life succumbs
While death and love, two kindred drums
Beat the time till judgment day
An actor in a passion play
Without beginning, without end
Evermore, amen

Being bitten by an ugly rat-thing (Braindead) or by a mutated sheep (Black Sheep). Well, in the latter case, you're a sheep zombie, but I suppose it counts.
