Please, zombies leave my brains alone,
It took years of schoolwork to get them grown,
There are not that many there,
That I have any brains to spare,
Besides, my skull is a really rock hard bone,
Addendum:
Biting my skull is so uncouth,
Besides, you might just break a tooth,
You see for you zombies I really care,
So, go get your brain food from elsewhere.
