If you can't be arsed to even stand and blow a whistle every now and then, why not assign the two most annoying and unpopular kids to referee a basketball match? It'll give them a little taste of power, bless, and will result in them getting pulped in the changing rooms by the losing team.
One team wins, one team gets to hit someone, and one bullied boy gets the whiff of authority that will drive him in adult life to start a corporation that menaces old ladies out of their homes so he can build a car park. Until that old woman works out how to reach the A-Team, at which point he'll cop a cabbage in the chops.
Everyone's a winner!
