Had a conversation with someone today:
Me: You know what I noticed about L4D?
Him: What?
Me: The "zombies" aren't really zombies.
Him: What makes you say that?
Me: Well, they're victims of a disease, not crawling legions of the undead.
Him: Then what do you suggest we call them?
Me: I'd say mutants, but then the survivors would sound like Space Marines.
