mischief managed, part VI

Just coincidence? Or have I two 2.5 year old, cold, calculated, cruel mischiefers (perhaps with a highly developed sense of humor) on my hands? This morning they emptied a box of cheerios on the floor downstairs, this afternoon they emptied a gallon milk on the floor upstairs. Unfortunately, I did not share their highly developed sense of humor as I mopped up milk and picked up cheerios.
