Teacher puts student in CAGE! Now waitressing

Is it possible to look at things like this in context?  It was a  dramatic joke.  Why do teachers resort to humor like this?  They spend a great deal of time attempting to control that segment of the class that reverts to shenanigans out of boredom.  You know: the kids that don't want to be there.  It is easy to sit there with a straight and somber face and question what thinking leads to this.  Ironically, it is the anal retentive,linear thinking, humorless teacher who never takes a risk that ends up keeping their job and makes school a hell for the ones that can't sit still.
