Oh my... several times. I used to have a bit of an ager/impulse control issue, and I've always been a big dude. Size+angry=holy walls. When I was dating the girl I married, she'd had some kind of cyst thingy removed from her insides. Her mom got into a screaming match with her, and I was worried about hemmoraging from the exertion. My GF stopped, but her mom kept it up. I open-hand slapped the wall next to her mom's head to puncuate my point, and put a 9"x7" hole in the drywall.
Thus did the screaming stop. Thus did I lean to patch drywall.
Ever been "greeted" by a large, slobbery dog? Like a Mastiff?
