Molly hunched over the rickety kitchen table in their dimly lit apartment, blueprints of the upscale community center spread out like a treasure map. Bill paced, twirling a fake mustache. "Okay, Molly, hit me with the plan. Kids' birthday bash—prime target for swiping those shiny presents. Balloons, cake, chaos. Perfect cover." Molly grinned, circling a spot on the map. "Right. We crash as party clowns. I'll be 'Jiggles the Jester,' you 'Boom-Boom the Balloon Man.' Sneak in at 2 PM, when the rugrats are hyped on sugar. Distract with pratfalls while you stuff the gift pile into duffel bags hidden in the bounce house." Bill snorted. "Bounce house? Genius, but what if some pint-sized detective spots us? 'Hey, mister, why's your balloon sack jingling with Barbies?'" "Improvise! Yell 'Magic trick!' and vanish into the piñata pile. We hit the exits at 2:30, before the piñata explodes and buries us in candy evidence. Load the getaway van disguised as the ice cream truck—free scoops for alibis." Bill laughed, slapping the table. "Alibis? We're pros. But if we snag that diamond-encrusted teddy bear from the rich kid's stack, we're golden. Just don't trip over a toddler on the way out." "Deal. Operation Present Pilfer—let's make it a birthday they'll never forget." Molly winked, folding the map.
