Further discussions with my children over various learning exercises in emotional control have lead to good-natured threats to post the offender's picture on SnivelingTurd.com.

This works with my (now) 6 year-old because it's a funny way to highlight the absurdity of a situation and "break the cycle" of being pouty, angry, whatever.

My 3 1/2 year-old seems to get a little upset about it, so I use it sparingly there.

Feel free to try it on your children!
