That's what we used to get from our mom in church.
That's called "yanking a knot in your head." haha
I have a friend who calmly pinches the crap out of her son's arm on the back just above the elbow when he is acting up in public. She keeps a smile on her face and lets him know there is more waiting for him at home if he doesn't behave and nobody sees what is going on. HEr son usually straightens right up.
