“Bill, this is the lowest point of my career, and I once robbed a magician during his own disappearance.” “Correction, Molly: we are not robbing children. We are liberating unattended assets from a poorly supervised joy warehouse.” “It’s a bouncy castle in a church hall.” “A temporary vault with balloons.” “You do realize tiny witnesses are notoriously observant?” “Please. Bribe them with cake, and they’ll testify the moon did it.” “There will be parents.” “Distractible, coffee-starved, emotionally defeated parents.” “And the clown?” “Natural enemy of order. We move during the balloon-animal phase.” “I hate clowns. They look like warrants with shoes.” “Focus. Entry through the side gate, past the bins, across the garden gnomes.” “The gnomes are new.” “Security upgrades. Stay nimble.” “What exactly are we stealing?” “Everything gift-shaped. Dolls, dinosaurs, suspiciously expensive educational tablets.” “If I end up fencing a karaoke unicorn again, I’m retiring.” “You said that last time, then named it and cried.” “It understood me.” “Right. I’ll create a diversion.” “With what?” “I’ll tell the dads the grill’s leaking gas.” “That’s reckless.” “That’s efficient.” “And if the birthday child sees us?” “We smile warmly and say, ‘We’re from the Present Inspection Bureau.’” “That’s absurd.” “Absurd works on adults. Children believe in justice.” “Fine. Masks?” “Party hats.” “Honestly, Bill, that’s inspired.” “I know.”
