Mom's corporal punishment of choice was the wooden spoon.
It didn't come down on my backside nearly as often as I deserved, but it was still about 50x as many times as my brownnoser sister got. Mom switched to other punishments when I laughed at her, sometime around my 11th birthday.
Dad, on the other hand, was not to be laughed at - and laughing at mom in front of him was a sure way to make sure I never did it again.
