Escalating the level of nonviolence

My son recently engaged in nonviolent direct action when he took over the bathroom after he was denied dessert.  I decided to escalate the level of nonviolence by threatening to deal with one's personal needs in his room.  He relented and I ended up reading him Saul Alinsky's retelling of the threatened O'Hare Airport Poop-in .  We both laughed very hard and a lesson was learned, hopefully.
