Night of the Living Bovines

Because sequels to zombie flicks are never-ending, it's easy to forget the mother of all zombie flicks:

"Seven cows, plump and attractive, came up out of the Nile and fed in the reed grass. Seven other cows came up after them, poor and very ugly and thin, such as I had never seen in all the land of Egypt. And the thin, ugly cows ate up the first seven plump cows, but when they had eaten them no one would have known that they had eaten them, for they were still as ugly as at the beginning. Then I awoke" (Gen 41:18-21).
