When Thomas Edison invented the lightbulb, he had trouble selling it. People just didn't trust this "new" way of making light. In order to promote his idea he decided to go around the country installing lights in different towns in order to drum up publicity.
While in Oklahoma, Edison stopped by an Indian reservation and offered to put lights in any building they wanted. After much thought the Indian chief decided that he wanted lights in his outhouse, so he could see what he was doing at night. This made him the first man to wire a head for a reservation!
