Molly hunched over the rickety kitchen table, maps and party invites scattered like confetti. Bill paced, twirling a fake mustache. "Listen, Bill, this gig's gold. Little Timmy's bash at the mansion—fancy folks, mountains of presents. We swipe 'em all while the kids are distracted by clowns." Bill snorted. "Clowns? We'll be the real jokers. How do we get in without turning into piñata fodder?" "Easy. I dress as the balloon lady—big hat, squeaky voice. You? The magician's assistant. Rabbit in the hat, but really, it's full of swag bags." "Rabbit? I'd rather be the cake guy. Roll in with the dessert trolley, load it with toys under the frosting." Molly laughed. "Brilliant! Kids swarm the cake, we snag the pile under the tree. Timing's key—hit at gift-opening frenzy." "What if the rugrats spot us? 'Hey, mister, why's your hat stuffed with teddy bears?'" "Improvise! Yell 'Abracadabra!' and bolt. Cops won't chase for stolen Barbies. We'll fence 'em online—'Gently used holiday cheer!'" Bill grinned. "You're a genius, Mol. World's dumbest heist, biggest payday." She winked. "For kids? We go in soft. Out rich."
