Molly hunched over the rickety kitchen table, blueprints of the community center spread out like a treasure map. Bill paced, munching on a pilfered donut, crumbs flying. "Listen, Bill, this is gold—er, presents," Molly whispered, eyes gleaming. "The 'Underwater Adventure' party for little Timmy's birthday. Balloons, cake, and a mountain of gifts from doting aunts and uncles." Bill stopped, donut halfway to his mouth. "Kids? We're robbing snot-nosed brats? Molly, that's low even for us. What if they cry? Or worse, throw tantrums?" She smirked. "That's the beauty! Chaos covers our tracks. We'll dress as party clowns—big shoes, red noses. Slip in during the piñata piñata-smashing frenzy." "Clowns? Me in floppy pants? I'd trip over my own feet and land in the punch bowl," Bill groaned. "And the haul? Teddy bears and toy trucks? We can't fence Elmo!" Molly leaned in. "Front 'em as collector's items. Or melt 'em down for... parts. Trust me, the parents will blame the magic show guy. We hit at 3 PM sharp—cake time, kids distracted." Bill sighed, wiping crumbs. "Fine, but if a toddler IDs me, you're explaining to the cops why Bozo's hauling a sack of Barbies." "Deal. Now, pass the donuts—we're celebrating our genius."
