“Bill, are you sure this is the target?” “Molly, the banner says HAPPY BIRTHDAY, and the building is guarded by a six-year-old with a paper crown.” “Terrifying.” “He’s holding a balloon sword.” “That changes everything.” “We need subtlety.” “I brought disguises.” “Why are you dressed as a magician?” “Because children trust magicians.” “Children distrust men carrying pillowcases and whispering about loot.” “Fine. What’s the plan?” “We enter during the musical chairs, blend with the parents, and collect presents from beneath the table.” “Then we escape through the kitchen.” “There’s a bouncy castle blocking the kitchen.” “We could bounce over it.” “I’m wearing orthopedic shoes.” “Then crawl under.” “My cape snags easily.” “Remove the cape.” “A magician without a cape is merely a man with poor judgment.” “We already are thieves, Bill.” “Professional thieves.” “Professionals don’t steal from children.” “We steal from capitalism.” “These presents include socks, crayons, and something labeled ‘Dad’s New Mug.’” “That mug is capitalism’s accomplice.” “Molly, listen. The birthday boy is approaching.” “Hide the pillowcase.” “Behind what?” “The enormous teddy bear.” “It’s looking at me accusingly.” “Teddy bears have no legal authority.” “It has a badge.” “That’s a sticker.” “We’re officially in trouble.”
