The basement smelled of damp socks as Molly spread the crayon birthday invitation across the wobbly table. Bill leaned closer, ski mask crooked, studying glitter with professional disappointment. "We are really stealing from six-year-olds now?" Molly whispered, wrinkling her nose. Bill shrugged and tossed a stale donut hole into his mouth, grinning. "Birthday presents are tax-free and unwrapped by suckers." Bill announced proudly. Molly snorted and unrolled surveillance photos stolen from the community board outside. "The invite says clown, magician, and two bored parents." Molly explained, pointing at the backyard map. Bill paced, tripping over traffic cones and plastic mustaches. "Perfect. We pose as entertainment. I love balloon animals." Bill suggested, practicing a creepy grin. Molly laughed, nearly knocking over their cupcake heist board. "You cried during balloon training. The poodle popped and traumatized you." Molly teased mercilessly. Bill clutched his chest and collapsed onto the sagging couch dramatically. "That poodle exploded like my dignity. Never again, okay?" Bill groaned, trembling. Molly unrolled a crayon blueprint, marking cake, exits, and presents mountain. "Fine. You distract the clown while I grab the gift table." Molly ordered, stabbing the map with a plastic pirate sword. Bill pulled his mask down, peeking miserably. "Why do I always get clowns? Last time one chased me." Bill complained loudly. Molly tossed him a red foam nose that bounced off his forehead softly. "Because you scream funny. It really sells our cover story." Molly giggled wickedly. Bill stroked an imaginary mustache, eyeing their dented getaway van outside. "Plan B if kids scream? Bribe them with stolen juice boxes?" Bill asked nervously. Molly shook juice boxes like maracas, dancing a tiny victory jig. "No witnesses, no mercy. We bring extra capri suns for silence." Molly declared firmly. Bill frowned at puppies and rainbows covering the invitation glitter. "Molly, this feels low, even for us. Puppies and rainbows everywhere." Bill muttered, ashamed. Molly rolled her eyes, calculating the price of one fancy robot toy. "Cheer up. One fancy robot toy pays our rent for month." Molly said brightly. Bill brightened, imagining paid rent and extra pizza for weeks. "Okay, Saturday at noon we crash Timothy's birthday like legends." Bill whispered, suddenly brave. Molly grinned and offered a sticky high five. "Deal. Bring van, masks, and absolutely no dignity left." Molly agreed, laughing. Bill straightened, trying to look like a professional criminal mastermind. "Agreed completely." Bill said solemnly. They shook hands over scattered sprinkles and stolen streamers, sealing their ridiculous pact with absolute seriousness. Outside rain tapped the tiny window while the van sputtered patiently. Molly folded the invitation neatly, tucking it into her jacket beside lockpicks and candy bribes. Bill loaded duffel bags, foam noses, and a suspicious magician cape from last Halloween. Somewhere a child practiced happy birthday on a recorder, off key and joyful. They looked at each other, half guilty, half thrilled, ready to crash Timothy's party, dodge clowns, outrun parents, and escape with mountains of brightly wrapped loot before cake on Saturday afternoon sharp.
