Has your toddler ever thrown a tantrum so bad you thought you might need to perform an exorcism?

It was at the OB when I was prego with my second... NO CLUE what started it!! All I remember was being beyond humiliated, somehow managing to get to the car... I was super hormonal to start with, so of course I started crying in the car, and my 2year old started repeating "sorry mommy, sorry mommy, sorry mommy" ... Not my best mommy moment but all I could do when I got home was ignore him, because I didn't want to get angry. He knew that he did something very very wrong and has NEVER done it again! Thank God...
