When I was in grade school, and first began reading some articles in our city's newspaper, I sometimes read about someone's body being found. After my mother explained that this meant the person was dead, I assumed it also meant that these dead people were often decapitated, since I pictured that these articles refered to finding dead people's bodies only -- as opposed to a body with a head.
