The van smelled of old coffee as Molly spread the blueprint across the dashboard. It was not a bank schematic. It was a crayon drawing of a bouncy castle, a clown, and a table labeled PRESENTS, taped to the windshield with a dinosaur sticker. Bill stared reverently. "Bill, we are stealing from a seven-year-old's birthday party?" Molly asked, tapping the pink cake in the corner. "Think bigger, Molly. Think bigger kids, bigger presents, bigger payoff," Bill whispered, adjusting his squeaky clown nose. Molly sighed and pointed to the side entrance marked with glitter glue. The plan was simple. Enter through the kitchen disguised as entertainers, distract parents with balloon animals, and wheel out the presents before anyone noticed. Bill had practiced making a poodle. "Your poodle looks like a diseased sausage, Bill," Molly muttered, watching him twist a red balloon until it popped. "That was modern art, Molly. The kids will absolutely love it," Bill insisted, sweeping shrapnel off his lap. Outside the house, balloons bobbed against the fence and a banner read Happy Birthday Leo! A mother carried juice boxes while children chased each other. The present table groaned under wrapped boxes. Molly pulled on a striped vest and an itchy red wig. Bill squeezed into oversized shoes that honked with every step. Their getaway vehicle was parked two houses down, its back doors open. "Remember, we grab the presents and leave the cake alone?" Molly said, double-checking the plan. "No, we absolutely take the cake too, for morale and sugar," Bill replied, licking his lips. "Bill, we cannot eat evidence in front of twelve witnesses," Molly snapped, yanking his wig straight. "Fine, we will share the evidence later, Molly dearest," Bill promised, honking his own nose solemnly. "And no honking while we steal, you squeaky disaster," Molly warned, glaring at his shoes. "My shoes only honk when destiny calls, Molly," Bill whispered, wiggling his feet. They marched toward the gate, where a bemused father with a spatula mistook them for entertainment. He waved them in, shouting kids had been waiting for clowns. Molly forced a smile. Inside, chaos reigned. Bill tripped over the bouncy castle tether and landed in the ball pit. Molly twisted balloons with speed of a Vegas dealer. While children crowded around her, Bill crawled toward the present table, dragging a laundry sack. Every step honked and every honk made Molly wince. "Hurry up before they realize we are not real clowns," Molly hissed through her painted smile. "Trying, these cursed shoes have a mind of their own entirely," Bill grunted, sweeping presents into the sack. A small boy in a party hat tugged on Molly's vest. "Are you stealing our presents, clown lady?" he asked innocently. Molly froze, her wig slipping sideways. "Stealing? No, we are taking them for super secret clown inspection, kiddo," she cooed, patting his head. "Does super secret inspection include taking the entire chocolate cake as well?" Bill whispered, already lifting the frosting masterpiece. He muttered "Run now please" softly and fled.
