The film stars Mr. Grimes, (or “Grimey” as he liked to be called), in a classic “Goofus and Gallant” scenario. Which role would you emulate? The hostile, shrieking Mr. Grimes who hands out detentions as if they were pennies wrapped in tinfoil on Halloween? Or the cool, mellow Mr. Grimes who one day lets it slip that he still lives with his mother. Of course you’d pick the first one. Whether he’s an effective educator is beside the point, because clearly the second one’s admission has lost him the respect of at least the next ten years of students who parade through his classroom. Find an eraser to hurl and synchronize your watches so you’ll know when to drop your textbooks. It’s time for Maintaining Classroom Discipline!
