Molly perched on the edge of a rickety stool in their cramped hideout, a map of the suburban backyard sprawled across the table like a treasure chart. Bill, her wiry partner with a mustache that screamed "amateur villain," paced back and forth, clutching a half-eaten doughnut. "Alright, Molly, the party's at noon. Kids everywhere, balloons popping like fireworks. We slip in disguised as clowns—big shoes, red noses, the works." Molly snorted, sketching a crude diagram with a crayon she'd pocketed from a previous gig. "Clowns? Bill, last time you wore face paint, you looked like a melted Picasso. We'll terrify the toddlers!" Bill grinned, crumbs tumbling from his lips. "That's the point! Chaos ensues, parents panic, and we grab the gift pile. It's stacked higher than my gambling debts." She eyed him skeptically. "And the getaway? On unicycles?" "Genius! Who suspects fleeing clowns on wheels?" Molly laughed, folding the map. "Fine, but if we get caught in a piñata brawl, you're the candy." As they high-fived, a stray balloon from their practice props floated lazily overhead, popping with a bang that sent Bill diving under the table. The heist was on—ridiculous as ever.
