My roomie and I love playing zombie hunting video games (Resident Evil, Left 4 Dead, Dead Rising, etc.)
In a moment of epiphany, I told my roommate that in all our playing of zombie killing games, we really take zombies for-granted. He said "how?"
I informed him that zombies were not superficial by any means.
His face twisted as he expected the worst.
I then concluded "zombies love people for their brains".
