Molly leaned over the rickety table in their cramped hideout, scribbling on a napkin with a crayon. "Okay, Bill, listen up. The party's at the community center—balloons, cake, the works. We sneak in as clowns. You distract the kids with balloon animals, I grab the presents." Bill scratched his head, eyeing the crayon map. "Clowns? Molly, I look ridiculous in a wig. What if they want tricks? I can barely juggle my own life!" She smirked. "That's the point! While you're fumbling, I'll stuff the gifts in my oversized pants. Easy peasy. Remember, no touching the cake—too messy." "Yeah, but what about the parents? One might recognize us from that botched Easter egg heist," Bill grumbled, sipping stale coffee. Molly waved him off. "Wear the nose! It's foolproof. We'll bolt before 'Happy Birthday' ends. Think of the loot—toys, gadgets, maybe a pony if we're lucky!" "A pony? In presents? You're dreaming. Fine, but if a kid cries, you're on cleanup duty," Bill sighed. "Deal! Operation Gift Grab starts at noon. Let's make those kiddos' tears our payday," Molly cackled, high-fiving him clumsily. Bill nodded. "To clowning around and getting rich!"
