Molly hunched over the grimy diner table, blueprints of "Little Timmy's Birthday Bash" spread out. "Bill, this is insane. A kids' party? We're talking squeaky toys and half-eaten cake." Bill grinned, chomping a fry. "Insane? Genius! No security— just snot-nosed brats and clown tears. We hit at piñata time. Chaos covers our grab." "Grab what? Barbies and slime eggs?" Molly snorted. "Rare stuff, Mol! Timmy's loaded—parents drop Rolexes in gift bags. We dress as entertainers. You: balloon princess. Me: face-painter with a sack hidden in my overalls." Molly smirked. "Balloons? You'll pop 'em fleeing. And the cake? Sticky getaway nightmare." "Nah, rented van disguised as the bounce house truck. Park out back, snag presents during 'musical chairs mayhem.' Kids chase each other—we swipe the pile. In, out in five." "What if a toddler IDs us? 'Mommy, balloon lady stole my Lego Death Star!'" Bill laughed. "We bribe with candy. Or drop a real piñata bomb—candy explosion, diversion supreme!" Molly sighed, folding the map. "Fine. But if I end up pied in the face, you're eating the evidence." "Deal! Heist of the century—presents pilfered, piñata pandemonium!" Bill clinked his soda.
