Molly adjusted her oversized clown wig in the rearview mirror, her face a mask of determination. Bill hunched beside her in the van, scribbling notes on a napkin with a half-eaten crayon. The colorful bounce house loomed ahead, echoing with shrieks of sugar-fueled glee. "We hit the gift table during musical chairs," Molly whispered, checking her utility belt stocked with juice boxes and tiny screwdrivers. Bill nodded, eyes darting. "I'll create a distraction with the piñata. You grab the goods. But what about the magician? Kid's got cards up his sleeve." They both snickered, the absurdity settling in. A birthday heist felt ridiculous even for them, but the haul of shiny new toys promised big black-market bucks. "Remember," Molly added, voice low, "no candy. It slows us down." Bill grinned, slipping on novelty glasses with fake noses. "Let's make this the merriest robbery ever." With synchronized nods, they stepped out, blending into the chaos of streamers and screams, ready to pilfer presents from tiny, unsuspecting hands. The caper of the century—or at least the most embarrassing one—had begun.
