Yoopers are descendants of the Vikings who first discovered Greenland. The word "Yooper" was coined by the Viking chieftan Erkki The Green when first sighting the new world he exclaimed, Yepper, it sure is cold here!" Yooper is Old Finnish for 'Yepper'.
Today's Yoopers are an odd mix of Finns, Frenchmen, Poles and Eskimos. They supply the lower Michigan 'Trolls' with essential things like casinos and prison space. The number one export of Yooperland is unemployment.
