Molly adjusted her oversized sunglasses and peered through the chain-link fence at the bouncy castle, where a dozen sugar-high kids were screaming like tiny banshees. “This is the worst idea you’ve ever had, Bill. And you once suggested we rob a funeral.” Bill crouched beside her, adjusting the fake mustache that made him look like a confused walrus. “It’s genius, Mol. Think about it. Twenty presents, all wrapped in shiny paper with bows the size of dinner plates. No alarms, no guards, just one stressed-out mom with a clipboard. In and out before the cake’s even cut.” Molly rolled her eyes so hard she nearly sprained them. “We’re career criminals. We’ve cracked vaults. We’ve dodged lasers. And now we’re crashing a six-year-old’s unicorn-themed birthday party? What’s next, stealing training wheels?” “Exactly!” Bill whispered, beaming. “Nobody suspects the clown. I’ve got the balloon-animal guy routine down. You’ll be the face-painting lady. We slip the presents into the big clown car while they’re doing musical chairs. It’s foolproof.” “Foolproof? You’re wearing a purple wig, Bill. You look like a grape that lost a fight with a lawnmower.” Molly sighed. “Fine. But if I have to sing Happy Birthday, I’m keeping the biggest teddy bear for myself.” Bill grinned. “That’s the spirit. We go in at peak chaos, right after the piñata breaks. Kids’ll be blind with greed. We’ll be invisible.” “Until some brat asks me to draw a unicorn on his face and I accidentally tattoo him with my criminal record,” Molly muttered. “And what about the parents? One soccer dad looks like he benches minivans.” Bill patted the comically large rainbow suspenders holding up his baggy pants. “I’ve got a whoopee cushion and a squirting flower. Non-lethal distraction devices. While they’re laughing at my tragic mime routine, you load the haul into the goody bags. We’ll be eating stolen birthday cake in the getaway van before the candles are even lit.” Molly stared at him for a long moment. “I hate how much sense you’re making right now.” “That’s why we’re a team,” Bill said proudly. “Brains and beauty.” “You’re neither of those things,” she replied, but she was already checking her utility belt full of glitter bombs. “Okay. One rule. No juggling. Last time you tried that you dropped a Fabergé egg.” “Fair,” Bill conceded. “But I get to keep the bubble machine. The bubble machine stays.” Molly groaned, then smirked despite herself. “If we get caught, I’m telling the cops you made me do it. I was just an innocent face-painter led astray by a man in squeaky shoes.” Bill offered her a high-five with his oversized novelty glove. “To the heist of the century. Operation: Birthday Bash and Grab.” She slapped his hand, sending the glove flying into a bush. “God help us. Let’s go steal some joy.” Together they straightened their ridiculous disguises and stepped toward the shrieking chaos, two of the world’s most competent thieves about to risk everything for a pile of plastic toys and discounted candy.
