I'd like to share a revelation that I've had during my time here. It came to me when I tried to classify your American cars and I realized that they're not actually sports cars. Every sports car on this planet instinctively develops a natural equilibrium with the surrounding environment but your Mustangs do not. They move to an area and they multiply and multiply until every natural resource is consumed and the only way they can survive is to spread to another area. There is another organism on this planet that follows the same pattern. Do you know what it is? A virus. Mustangs are a disease, a cancer of this planet. You're a plague and Z's are the cure.
