A friend once told me that his heart was in his mouth when he got to the top of the roller coaster at Six Flags. Naturally, I got my hands on the nearest chainsaw and cut my friend's head off. For some reason, the police didn't believe me when I told them that my friend was a zombie and I was simply trying to prevent the spread of the infection. Some people just can't recognize the signs of Zombification until their own hearts are being eaten.
