The van smelled like old crayons and desperation. Molly had parked it two houses down from the screaming. Across the street, a bouncy castle wheezed under the weight of seven sugar-high eight-year-olds. Streamers flapped. A clown made a dog that looked more like existential dread. Bill stared at the mountain of brightly wrapped presents through binoculars. "Molly, are we really going to rob a kids party?" He lowered the binoculars slowly. "We are professionals with standards. This feels new and low." Molly didn't look up from her clipboard. "We have standards. We standardly need money. Rent is due, Bill." She tapped the paper. "Besides, look at that pile. That little monster Timmy is getting spoils we could flip fast." Bill fidgeted with his fake mustache. "My mom says stealing from children gives you seven years bad luck or something." The clown outside popped a balloon animal. Children screamed with delight. "Your mom also thinks the microwave spies on her, so her credibility is shaky at best, dear." Molly pulled two oversized clown shoes from a duffel bag. "Plan is simple. You distract parents with magic tricks while I grab the loot and run." Bill stared at the shoes like they might bite him. "I don't know magic. I know how to open safes and lie to customs agents." She tossed him a squeaky flower. "Then lie convincingly that you are a magician. Same principle, bigger hats, less prison time." Outside, the birthday cake arrived, a towering chocolate monstrosity with sparklers. "What if they recognize us? We are two adults without kids at a kids party. That's suspicious." Molly laced the clown shoes. She stood, now six inches taller and deeply unserious. "They won't recognize us. They will see Bernard and Brenda, children's entertainers extraordinaire, here to spread joy." Bill sighed and put on the rainbow wig. It itched immediately. "Fine, but if one kid cries because I stole his dinosaur truck, I am keeping it." Molly grinned, opening the van door. The children's music hit them like a wave. "Deal. You can keep one toy. Let's go steal some childhood dreams before naptime ends." They waddled toward the yard, shoes squeaking, dignity already abandoned at the curb. "Remember, act natural. Big smiles, silly voices, and absolutely no mention of our outstanding parking tickets." Bill attempted a smile. It looked like he was passing a kidney stone. "Like this? Do I look like a trustworthy clown who definitely did not plan a felony?" Molly patted his shoulder. The flower squirted water in his face. "Perfect. Terrifying. Let's go rob Timmy blind." The gate was open. The presents awaited, glittering. "After you, Brenda." "After you, Bernard. Try not to trip." They stepped inside as the children turned, thirty small faces lighting up with pure unfiltered hope. For a second, even Molly felt a pang of guilt before remembering the landlord. Then the bouncy castle deflated loudly behind them. Very dramatically. "Oops. Who hired these clowns?" "We did. Unfortunately." "Showtime, Bill." "Let's boogie."
