Not sure what brought this on, but it’s been running through my head all afternoon.  It should be sung in the same manner as this old chestnut.

Zombie horde shambling down the strip
Zombie hunters on a containment trip
Mission: Eradication
Destination: Hot Zone
Don’t wanna fight those zombies alone!

Kneel down, aim straight, take your first shot!
Nothing but head shots will do squat!
Body shots don’t count, aim for the head!
You don’t have enough bullets for all these undead!

If my rifle it should jam,
Zombie gonna eat me like Christmas ham!
If I get caught in a zombie’s bite,
Leave me a grenade and I’ll continue the fight!

If I die in the zombie war,
Burn my body just to be sure!
Throw some zombies on my pyre!
Kill those zombies with my fire!
