Molly adjusted her oversized clown wig in the rearview mirror, her face smeared with greasepaint that made her look like a deranged birthday nightmare. Bill slouched beside her in the van, fiddling with a comically large pair of bolt cutters disguised as party favors. "Remember, we hit the gift table during the cake smash," Molly whispered, scanning the balloon-filled driveway. "Those kids won't know what hit them." Bill snorted. "This is insane, Mol. We're stealing from toddlers. What's next, robbing the tooth fairy?" "Focus," she hissed, elbowing him. "You distract with the magic tricks while I bag the loot. Think of it as... redistribution of joy." "Redistribution of joy? We're gonna get haunted by vengeful six-year-olds." They crept toward the backyard where squeals of laughter pierced the air. Molly's heart raced with the familiar thrill of the score, even if the target was a pile of brightly wrapped boxes guarded by hyper children. "Last chance to back out," she muttered. Bill grinned wickedly. "Nah. After this, we're legends. The Bonnie and Clyde of the bouncy castle circuit." They slipped through the gate, ready to execute the most ridiculous heist of their careers.
