WOW, I don't think I can really top these
Crash has only messed with something one time in his 3 year old life. Which wasn't that bad at all. However Bosco has chewed up pillows, (It looked like it snowed 5 inches in my living room) rugs, newspapers and tore my carpet into shreds when he had to wear his cone. He hasn't done this in a while though.
However if you leave the telephone and remote control out, it will be in pieces when you return home.
Needless to say, I feel very lucky with my two boys.
