Few things are more painful than stepping on a Risk board piece in your bare feet.
A Monopoly red hotel is pretty painful! :-)
My wife was reclining in a lazy boy right next to the stool next to the kitchen counter. Not to disturb her I just stepped over the stool. I hadn’t seen the Hot Wheels fire engine my son had left on the floor on the other side of the stool. I realized what was happening but couldn’t stop my weight from shifting. All my weight was on one bare foot on top of a square fire engine.
