"So the mark is turning six today?" Molly asked, checking her watch. "Seven," Bill replied, adjusting his wig. "Seven. What are we looking at for security?" "Two bouncy castles and an exhausted mother. We bypass the juice box station and hit the gift table during the piƱata drop." "Brilliant strategy. What are our disguises?" "Clowns," Bill said with a completely straight face. "I am absolutely not wearing the squeaky nose." "You must wear the red nose, Molly. It thoroughly sells the illusion." "The illusion that professional cat burglars want to ruin a birthday?" "Think of the loot! Unopened Legos, rare action figures, maybe a drone. Think of the resale value!" "Fine. I handle toddler crowd control while you bag the wrapped presents." "Deal. I will pull the getaway van around the alley." "Wait, what if the birthday boy demands a balloon animal?" "I spent three hours learning to make a poodle." "Yesterday you made a pathetic lumpy sausage." "It was a dachshund! Just distract the little monsters with your horn." "If a sticky child bites me, I am taking your entire cut of the Barbie Dreamhouse." "Fair enough. Grab the oversized foam shoes. We have a party to rob."
