Well yeah, you've got 5 kids! If it wasn't they'd all be dead by now, either from them getting into something or you killing them for breaking stuff. With me, it'd be the latter. ;o)
LOL! Actually, the worst thing I've ever had one of the kids do was cutting up a comforter set I had just bought. My son was fascinated with scissors and one day I caught him cutting up the dust ruffle. He was about 3 years old at the time. Needless to say, I was plenty peeved.
