(This started as a joke one day when I was cleaning my yard. There were lots of banana trees, and it turns out being really hard to remove them — they have this pod-like structure deep in the ground that must be removed, otherwise they will grow again. Since I don't like bananas and I read that all banana trees share the same DNA, I came with the theory that they are in fact aliens. They come to Earth on the pod-like structure, and they dominate everyone who eats banana. When the aliens rise I will be the only one able to fight them, since I don't eat bananas.)
