You know those noise trackers they have in classrooms, the one's that make a loud noise when you're being too loud? Having one of those in a session, with a punishment whenever it goes off.
My PERSONAL vision is a bunch of lers sitting around while one works a lee over and there's a timer set to go off in an hour. And every time BEFORE that hour is up when they make too much noise, another ler gets to join.
