Molly adjusted her clown wig in the dimly lit van parked outside the bustling suburban house, where kids' laughter echoed like tiny alarms. Bill, fiddling with a fake mustache, grinned maniacally. "Alright, Molly, Operation Gift Grab is a go. We crash this kiddie bash as entertainers—I'll juggle, you do balloon animals," Bill whispered, eyes gleaming. Molly snorted. "Juggle? You can barely handle your own shoelaces. And balloon animals? Last time, you made a snake that looked like a deflated dream. What's the exit strategy?" Bill leaned in. "Simple: We load the presents into giant sacks disguised as piñatas. While the rugrats are whacking away at candy, we bolt with the loot. Easy peasy!" "Easy? What if a kid spots us? 'Hey, mister, why's your piñata full of Xbox games?'" Molly mocked, rolling her eyes. Bill chuckled. "Improvise! Tell 'em it's Santa's early delivery. Or distract with more cake—kids love cake." Molly paused, smirking. "Fine, but if we get caught, you're the one explaining to the cops why we're dressed like rejects from a circus nightmare." "Deal! Now, let's go steal some birthday joy," Bill said, high-fiving her awkwardly. They slipped out, hearts pounding with goofy excitement.
