Hmmm, signature dance move. Let's see: jog up the stairs to investigate mysterious toddler screaming, pirouette left to avoid a pile of Legos, leap over the Hot Wheels, throw oneself bodily between two boys trying to hurt each other, bow and grab the shin kicked in the melee, wrestle combatants into separate corners, use a firm right hand to lay down the law, turn a deaf ear to the protests, square your shoulders and exit stage right. A masterful performance deserving of an encore. Next showing in twenty minutes.
