A disease that transforms you into a North American Yeti. A North American Yeti is a harry all over except for the head, which is bald. They live in North America (duh!) and really like the Chicago Bears. They also argue a lot, and are ill tempered. They have bad manners, and will closeline you as well if they get angry, using their over developed forearms.
