Molly adjusted her fake mustache in the rearview mirror while Bill crammed another handful of Cheetos into his mouth from the driver’s seat. “This is the dumbest idea you’ve ever had,” he mumbled around the orange dust. “It’s brilliant and you know it,” Molly shot back. “Kids’ birthday party. Twenty screaming six-year-olds, one stressed-out mom, zero adults paying attention. The presents are just sitting there like shiny little idiots begging to be adopted.” “Adopted. That’s what we’re calling grand larceny now?” “Focus, Bill. We hit the bounce house first. I’ll create a diversion by pretending I’m the hired magician. You slip in as the disgruntled balloon animal guy.” “I don’t know how to twist balloons, Mol.” “That’s why they’re disgruntled, genius. You just wave a half-inflated wiener dog around and look disappointed. Kids won’t notice. They’re distracted by sugar and existential dread.” Bill licked Cheeto dust off his fingers. “What if they’ve got one of those face-painting ladies? Last time I saw one of those I almost cried because she turned me into a ‘brave knight’ and I looked like a depressed zebra.” “You’ll live. We go in at peak cake time. When that mom yells ‘who wants ice cream?’ we make our move. I’ll yell ‘Abracadabra’ and pretend to pull a rabbit out of my hat. Except the rabbit is you in the backyard grabbing the gift table.” “That’s a terrible magic trick.” “It’s performance art. While they’re all clapping for the rabbit that isn’t there, you shove the presents into the duffel bag shaped like a giant teddy bear. I spent three hours hot-gluing googly eyes on it. Show some respect.” Bill sighed. “What about the birthday kid? Kid’s gonna be crushed.” “Kid’s getting a Nintendo Switch from Grandma. We’re doing the family a favor. Less fighting over batteries on Christmas morning. We’re basically therapists.” “You’re insane.” “I’m a visionary. Now, the get-away. I’ve got the ice-cream truck parked two blocks over. We ditch the costumes, blast ‘Pop Goes the Weasel’ and disappear into suburban traffic like the criminals we are.” “Ice-cream truck? Where did you even—” “Borrowed it. Don’t ask questions you don’t want the answer to. You just have to sell sprinkles if anyone flags us down. Act natural.” “None of this is natural, Molly. We’re grown adults planning to steal Barbie dreamhouses from toddlers.” “Exactly. The absurdity is our greatest weapon. No one will believe it happened. The cops will think it’s some kind of performance prank. By the time they figure it out we’ll be three states away eating stolen Funfetti straight from the box.” Bill stared at her for a long moment. “I hate how much sense you make when you’re clearly deranged.” “That’s why we make such a good team. You provide the moral hesitation, I provide the chaotic momentum. Now put on the stupid clown wig. We’ve got a heist to ruin some poor child’s sense of trust in the world.” “God help us,” Bill muttered, reaching for the rainbow afro. “God’s busy. We’ve got the balloon animals.”
