Welcome to Zombieland, please keep your hands and feet away from the dead

Open your mouth beautiful
show me those rotten teeth
I have then in my sights
and a shovel to swing

I break your face
You moan for more
Then your brain is gone
Alas, no more for you, undead whore

Hey look a M1911
Loaded up and ready to go
headshots like a beast
and guts rain down like red snow

Here comes the cavalry
the sound attracts
A AR-15 mows them down
so much for their attack

On the summit of the mountain,
the mountain of bodies
I see a golden ray of light
on top of the prize, a Twinkie
