Molly adjusted her fake clown nose and glared across the greasy diner table. “Bill, if you say ‘it’ll be a piece of cake’ one more time I’m shoving this wig down your throat. We’re robbing a children’s birthday party, not the First National Bank.” Bill grinned around a mouthful of pancake. “Relax, Mol. Kids are easy. They’re distracted by sugar and a guy in a dinosaur costume. We slip in during musical chairs, grab the gift table, and waddle out before the piñata drops.” “Waddle? You’re wearing the giant duck suit, remember? I’m the depressed mime. I already practiced my silent crying in the mirror. It’s Oscar-worthy.” “Fine, fine. Duck it is. But we need a signal if the parents get suspicious. How about I quack twice?” Molly pinched the bridge of her nose. “You quack at all and I’m leaving you handcuffed to the bounce house. Look, the birthday girl is turning seven. Her name’s Madison. She’s obsessed with unicorns. We tell the mom we’re from ‘Magical Moments Entertainment’ and that the real performers are stuck in traffic. Classic.” Bill slurped his coffee. “What if Madison wants us to do magic tricks?” “You do the magic. I’ll stand behind you making it rain confetti and regret. Just don’t pull a rabbit out of your duck tail like last time. That thing was traumatized.” “Hey, the rabbit got a modeling gig after that. Positive PR. Alright, timeline: we hit the party at two-fifteen. Cake’s been served, sugar rush is peaking, adults are half-dead on grocery-store wine. I create a diversion by ‘accidentally’ releasing two dozen balloons into the ceiling fan.” “Balloons into a ceiling fan? Bill, that’s how we get sued.” “Exactly. Chaos is our friend. While they’re chasing squeaky latex carnage, you wheel the gift table out the back door pretending it’s part of a magic act. I follow once I’ve ditched the duck head. We meet at the van behind the bouncy castle.” Molly tapped her fork against her plate. “And the getaway vehicle is definitely not the one with the giant ‘Clown Car Rental’ sticker this time, right? I still have nightmares about that soccer mom chasing us down the highway.” “Completely unmarked. I borrowed my cousin’s plumbing van. Smells like regret and drain cleaner, but it’s clean. Mostly.” She sighed. “We split the haul sixty-forty because I’m the one who has to look heartbroken when the mime makeup runs. Also, if we accidentally steal the wrong unicorn plushie and some kid starts crying, I’m giving it back. I have limits.” Bill leaned forward, eyes sparkling. “Molly, we’re talking iPads, designer sneakers, and whatever rich parents wrap in two-hundred-dollar paper these days. This isn’t stealing. This is… redistribution of birthday wealth.” “Call it whatever helps you sleep, duck-boy. Just remember: if we get caught, I’m selling you out faster than you can say ‘honest mistake.’ I’ll tell the cops you kidnapped me and forced me into grease paint.” He laughed. “Fair. Ready to go ruin a seven-year-old’s party?” Molly slid her sunglasses on and gave a grim nod. “Let’s make some terrible memories.”
