SPN: Zombie Dean

I was pretty upset when Dean died...but then I thought, "oh, he can be a zombie!" and zombie!Dean came to be. What's he singing?

"We’ll put this thing to bed
When I bash your head open

All we want to do is eat your brains
We’re not unreasonable; I mean,
no one’s gonna eat your eyes
All we want to do is eat your brains
We’re at an impasse here;
maybe we should compromise:
If you open up the doors
We’ll all come inside and eat your brains."

Faaaavorite filk song. Up there with "Weiss & Hickman".
