What did your toddler do that made you so mad you thought you were gonna lose it?

i ask because my 4 year old just jumped on his etch-a-scetch and it shattered (by the way, had no idea they could break like that). - so now he is in a SERIOUS time out and i am here trying to calm down so i don't lose it. - oh, this after he scd his spiderman toy on the brick fireplace and rubbed the paint off and then cried because spiderman had no eyes.... i won't even get in to how he wants to wrestle with his 21 month old sister...
