Grade School: Spankings, take students who are fighting on the playground to the gym give them boxing gloves and let them go for it. <br />
High School: Bringing a knife or gun, building a gun cabinet in wood class, hazing, having the teachers take the seniors (who are old enough) to have a drink before graduation.
PC has nothing to do with it, but paddling. Not just paddling, but using a wooden instrument to beat the hell out of the student's as*s.
