Grey's Anatomy

I was quite disappointed that my theory on the meaning of "Code Black" was proven false. Based on the preview, I was pretty sure that Code Black stood for Zombie Attack. Wouldn't that have been more interesting than the tired old "live ammunition in a body cavity" episode we've seen time and time again? I bet zombies would have put Meredith out of her misery pretty effectively. Unless she stops moping over stupid Patrick McDreamy on the double, I will continue to hope for zombies.
