Ouch, I feel for you man. That hurts just reading it! I don't have kids myself, but when my sister's kids were younger there were a few close calls!
One of the worst thing that ever happened to me Joe-wise was ages ago when I painted the gun station seats from the Rolling Thunder and left them outside to dry. I came back out a little later to find my dog, who was only a puppy then, had jumped up on the table and chewed them all up!
