Molly adjusted her oversized clown wig and peered through the hedge at the bouncing castle. “Bill, this is the dumbest idea you’ve ever had, and you once tried to rob a police station with a water pistol.” Bill grinned, adjusting his fake mustache. “Think about it, Mol. Twenty screaming kids, one stressed-out magician, and a mountain of brightly wrapped loot nobody’s guarding. We’ll be in and out before the birthday boy blows out his candles.” “We’re stealing from children,” Molly hissed. “I have standards. Low ones, but they exist.” “Standards?” Bill scoffed. “You once pickpocketed a nun. These presents are basically begging to be liberated. We’ll wear the stupid costumes, blend in, and swap the gifts with empty boxes. By the time they open them, we’re halfway to Mexico with Xboxes and whatever else rich kids get these days.” Molly sighed. “If we get recognized, I’m blaming your mustache. It looks like a depressed caterpillar.” “Fine. But I get the piñata. That thing’s bulging with candy and miniature greed. Come on, partner. One little party. What’s the worst that could happen?” “Famous last words,” Molly muttered, tugging her rainbow suspenders. “Let’s go ruin some childhoods.”
