Between Left 4 Dead, and The Last Guy, I think something got into my head.

Since the Zombies Came

Since the zombies came, you can’t get decent sushi;
Zombie sludge, it spoils fish like nothing doing.
And all the second hand stores, they had to close up shop…
Stains just don’t wash out the way they used to, do they?

Stuff that’s better – well, the horror flicks, of course. Duh.
Extras just show up. And don’t need paid, or credit.
Watch at home, though! Darkened cineplexes…
Real bad news. Though crowds are thinner at the malls now.

‘Sides, the zombies, mostly peaceful, right? Like yoga,
Tai chi, meditation, all that shit. OMMMM, then
Nom nom BRAAAIIIINS. They mostly stand and stare in corners
Seeing into places we cannot with jelly

Eyes and dreaming of the sushi and the clothes, the
Pay and credit, ordinary hungers (BRAAAIIIINS), good
Posture, faces still intact, more moods than one… sad.
Pity them; resent them, for the sushi’s sake.

Worse? It could be worse, sure. Aliens are worse, right?
Zombies get you, BRAAAIIIINS, you’re dead, undead, whatever.
Aliens, you live on screaming, tentacles in
Awkward places, slaved. I’d rather eat my friends, thanks.

Trochaic hexameter, FWIW.
