Oh man, we've had weeks like this too. My youngest in particular seems to bruise if you look at her funny.
It reminds me of something I read years ago in Reader's Digest or Good Housekeeping or something. A woman's young daughter had broken her arm and the running joke at their house became, "If you don't stop (insert action) then I'm going to break your other arm." So one day at the grocery store the girl, in her cast, is in a long line with her mom and fussing with the candy in the rack. The mom says, "Please stop playing with the candy." To which the kid replies in a nice, loud voice, "Or what, Mom? Will you break my other arm too?"
