I know nothing about kicking children in the teeth, but I will say that when I attended school, the paddle with holes drilled in it that hung on the edge of the blackboard was a damn good behavior modifier. We weren't the smart assed rowdy bastards so many kids are today. I know, I have two of my own. While I don't advocate corporal punishment for children as a rule, I agree somewhat with the old saying "spare the rod and spoil the child".
