As a child, you accidentally fell asleep on the couch one night while watching the Discovery Channel; however, the thing that believes it is you (which you know as your body) stayed awake for several hours thereafter. During that time, it learned everything there was to know about chameleons from a National Geographic special. Just before you regained consciousness, a stray curl of your hair snapped a horsefly from the wall, beginning a long and terrible process of transformation.
