The Maniacs of Orofino, Idaho are kind of odd.
http://www.sd171.k12.id.us/ohs/index.htm The town of Orofino has an Idaho State Correctional Institution that was a mental hospital. They claim the high school mascot has nothing to do with the state mental hospital or the prison but I have a hard time believing that.
I've always like Penn's Quakers because the thought of Quakers fighting is oxymoronic yet amusing.
