We're Not Unreasonable

KATE: Not if he were the last man on earth.
SARAH: Ever.
KATE: Ever.
SARAH: Even if everyone else was eaten by zombies.
KATE: Ha! How on earth did we manage to survive that?
KATE: I figure we'd be the first to go.
SARAH: Because we are resourceful?
SARAH: Because of underpants?
KATE: Ah. Yes. Because of underpants.
KATE: Zombie-resistant underpants.
SARAH: Yes. They keep the zombies out and the boys in?
KATE: Sounds good to me.
KATE: But wait--what if it's a boy zombie?
KATE: Which takes precedence?
SARAH: Zombie always comes before boy.
SARAH: We don't want any zombies at all.
KATE: That's wise.
SARAH: Then again, we don't want all boys.
KATE: Well, no.
KATE: But surely we'll have some say in that part.
SARAH: Invitation-only underpants.
KATE: You can't really decide with zombies.
KATE: "No, I don't want you to attack me. You? You're okay though."
KATE: Nope.
SARAH: As long as no one eats your eyes.
