Dr. Millard Rausch quotes from Dawn of the Dead (1978)

The normal question, the first question is, are these cannibals? No, they are not. Cannibalism in the true sense of the word implies an interspecies activity. These creatures cannot be considered human. They prey on humans. They do not prey on each other, that's the difference. They attack and they feed only on warm flesh. Intelligence? Seemingly no reasoning ability, but basic skills remain from a remembered everyday life. There have been reports of these creatures using tools. But even these are the most basic, the use of tools as bludgeons and so forth. I might point out that even animals have been known to adopt the use of tools in this manner. These creatures are nothing but pure, motorized instinct. We must not be lulled by the concept that they are our family members or our friends. They are not. They will not respond to such emotions.

We are down to the line, people. DOWN TO THE LINE!

Dummies. Dummies.
