In the shadowy corner of an abandoned playground, Molly and Bill crouched behind a slide, their eyes fixed on the nearby house where a children's party was in full swing. The air was filled with the scent of popcorn and the sounds of joyful squeals. These two seasoned thieves had sunk to a new low, targeting birthday presents from innocent kids, but the economy was bad and the pawn shops were paying top dollar for unused toys. Molly adjusted her oversized bow tie while Bill checked the contents of his utility belt filled with balloons and whoopee cushions. Their plan involved infiltrating the party as surprise clowns. They would perform a few silly acts to win over the crowd, then during the gift opening, they would swap the real presents with empty boxes and make off with the goods in their tricked-out ice cream truck. It seemed foolproof, except for the potential of tantrums and parental interference. The duo reviewed their timing one last time. Everything hinged on the moment the birthday cake arrived. "We hit the presents after cake," said Molly. "Right, but avoid the pony," Bill answered. "Got it, let's not get caught by toddlers," she added. They high-fived awkwardly.
