Okay, it's a catchy folk-style ballad about zombies. And it's been in my head for about a week.
I mean, how can you resist a chorus like *singing* :
All we want to do is eat your brains!
We're not unreasonable....I mean, no one's going to eat your eyes...
Okay, not for everybody I suppose, but I was laughing my head off. Here's Jonathan Coulton, performing "Re: your Brains". Enjoy!
