The name of the school I went to was "Beall" (rhymes with "Hell"), so naturally we'd do a chant at football games that ended with "Give 'em hell, Beall". Never got any complaints from the other team, but the principal of the school hated it.
edit -- as for knowing nearby county names, I was a geography nerd in high school, so I memorized all the counties in Maryland (there aren't that many of them), but around here I only know the ones I need to know to understand tornado warnings. If the tornado is in Pottawatomie County, it's headed away from here. If it's in Cleveland County, it's here. If it's in McClain or Grady County, it's not here yet but moving in this direction.
