My students, in general are not defiant. They are impulsive, and are sometimes easily distracted. Practical jokes? Sure, but not mean-spirited jokes, for the most part. They wouldn't dare pull something like that with me, because they'd then spend the rest of the year looking over their shoulders, waiting for my return salvo and wondering what form it might take.
They also read me; we know each other pretty well. They know that the quieter I get, the more irritated I am and the less likely I am to be patient with any forms of disruption. Almost all of the time, all it takes is for me to get quiet, and so do they. I very, very rarely need to apply any extreme measures, but when I do they are memorable enough to serve for a long time after.
The fictional and stereotypical situation in this clip is dated; those characters come from a generation in which getting trouble at school meant worse trouble at home. Those days are, for the majority, long gone.
