that the kid falls down the stairs at the exact moment you have the big dog in the bathtub covered with shampoo? The kid is fine--couple of bruises and a goosegg on her head--but boy is my bathroom wet! Oh well, I guess it's one way of getting the floor clean! Oh yeah--this was AFTER I demonstrated for the kids why you don't try to push the strawberries down into a moving blender! Love my little roomba doggie!
