Molly hunched over the blueprint of the suburban backyard, her eyes gleaming with mischief. "Okay, Bill, listen up. The party's at noon—balloons, cake, screaming kids. We sneak in as clowns. You distract with balloon animals, I'll grab the presents." Bill scratched his head, spilling coffee on the map. "Clowns? Molly, I look like a scarecrow in makeup. What if they want a rabbit? I can barely tie my shoes!" She rolled her eyes. "Improvise! Say, 'Abracadabra, here's a snake!' Then, while they're laughing—or crying—I swoop in. The gift table's by the bounce house. Easy peasy." "But what about the parents? They're like hawks. One wrong move, and we're toast." Molly grinned, twirling a fake mustache. "That's why we go full commitment. Honk your nose, juggle oranges. I'll stuff the sacks under my polka-dot pants. Out in five minutes, tops." Bill sighed. "Polka-dot pants? This is humiliating. Remember the museum job? We almost got caught 'cause you tripped on your stilts." "Shut it! This is gold. Kids' presents—toys, gadgets, maybe cash envelopes. We'll fence 'em downtown. You in or what?" Bill nodded reluctantly. "Fine. But if a toddler pukes on me, you're buying the beer." "Deal," Molly laughed, high-fiving him. The plan was set—ridiculous, but foolproof in their minds.
