Molly and Bill crouched behind a hedge, the muffled sounds of shrieking children and birthday songs drifting over the fence like a sugar-coated nightmare. The plan was simple, yet brilliantly stupid. "We hit the gift table at cake time," whispered Molly, adjusting her tiny party hat. "Kids are distracted, parents are drunk on punch." Bill peered through a gap in the leaves, eyes wide. "Molly, they're singing 'Happy Birthday' like it's a war chant. What if they turn on us? I've seen what toddlers do to piñatas." "Relax, we'll be the clowns. Literally. I stole these noses from the costume shop." She flicked his bright red proboscis. "We go in, cause a diversion with the balloon animals, swipe the presents, and vanish before the candles are blown out." Bill sighed. "Last time we stole from children, I had nightmares for weeks. They bite, Mol." She grinned, already crawling forward. "That's why we bring the emergency lollipops. Distraction grenades. Now shut up and practice your goofy laugh—we're about to ruin the best day of some six-year-old's life." They slipped toward the gate, ridiculous shoes squeaking, hearts pounding with the thrill of the dumbest score of their careers.
