A Nebraska lawmaker wants to allow teachers and administrators to carry guns, and that sound you heard was the collective shudder of thousands of adults across the state remembering that one teacher -- you know the one, every school had one: stressed, bitter, rumored to have slapped a kid once, chainsmoked four cigs and gulped three cups of whiskey-laced coffee in the teacher's lounge just before heading into a stuffy, smelly room with 30 eighth-graders. Now, imagine him packing heat. Oy.
