Molly leaned against the van's dashboard, eyeing Bill with a smirk. "Alright, genius, what's the play? We're crashing a kiddie bash at the mayor's mansion. Presents galore—think iPads, bikes, the works. How do we snag 'em without ending up on Santa's naughty list?" Bill chuckled, adjusting his fake mustache. "Easy peasy, Mol. We go in as clowns. You know, big shoes, red noses—the whole nine yards. Kids love clowns! While you're distracting 'em with balloon animals, I'll swipe the gift pile. 'Hey kids, who wants a puppy-shaped balloon?' Bam, they're hooked." Molly snorted. "Clowns? Bill, that's your brilliant idea? Last time you tried balloon animals, it looked like a deflated giraffe in distress. And what if the parents spot us? 'Excuse me, sir, why's your clown suit bulging with Barbies?'" "Details, details," Bill waved her off. "I've got diversions: smoke bombs disguised as party poppers. Pop one, chaos ensues—kids screaming, parents panicking. We grab the loot and bolt to the piñata van outside. It's foolproof!" "Foolproof? You're the fool, Bill. Fine, but if we get caught, I'm blaming your clown phobia. Remember that time in Reno?" Bill grinned. "Hey, that was a mime, not a clown. Totally different. Let's do this—presents await!"
