Molly adjusted her fake mustache in the dimly lit van parked outside the bustling suburban home, where balloons bobbed like drunken sentinels and the air thrummed with the chaotic symphony of squealing children. Bill, her lanky partner in crime, fiddled with a grappling hook disguised as a piñata stick, his eyes wide with a mix of excitement and dread. "This is genius," Molly whispered, peering through binoculars at the pile of glittering presents under a candy-striped tent. "Kids' parties are goldmines—wrapping paper everywhere, no one counts the gifts." Bill gulped, wiping sweat from his brow. "But what if they spot us? We're not exactly blending in." She smirked, handing him a clown wig. "Relax, we'll go in as entertainers. You juggle, I distract with balloon animals. Grab the loot during the cake smash." The plan was absurdly simple: infiltrate the birthday bash of little Timmy Hargrove, whose parents were notorious for over-the-top celebrations. Molly envisioned the haul—video games, bikes, maybe even that remote-control drone she'd always wanted. Bill, ever the pessimist, imagined jail time with finger paints. "Ready?" Molly asked. Bill nodded reluctantly. "As I'll ever be." They slipped out, hearts pounding to the rhythm of "Happy Birthday."
