Whenever one of the kids gets in trouble, they get middle named. Their first and middle names snapped in a sharp tone means they'd better knock it off now or else.
Today George was a hot mess and Adam said, "GEORGE DAVID, knock it off!" several times. Of course this made George frustrated with Adam and at one point, George snapped, "DADDY DAVID, stop!"*
Adam was laughing so hard he left the room!
*Adam's middle name is not David but it makes perfect sense that George would think George David= trouble, Daddy David (middle name) would equal the same thing!
