Molly spread the blueprint across the diner table. “The party’s at noon, Bill. We slip in, steal the presents, and vanish before anyone notices.” “Excellent,” Bill whispered. “What’s our disguise?” “A clown.” “I’m allergic to clowns.” “You’re allergic to competence.” Bill studied the map. “There’s a bouncy castle guarding the back door.” “Then we bounce.” “On purpose?” “Preferably.” They arrived wearing oversized party hats and carrying a suspiciously empty piñata. Molly marched toward the garden gate while Bill practiced an innocent smile that looked medically concerning. “Remember,” Molly said, “we’re entertainers.” “I can juggle.” “You can drop three oranges.” “That’s practically juggling.” A girl blocked their path. “Are you magicians?” “Absolutely,” Molly said. “Observe!” She snapped her fingers, and Bill vanished behind the gift table. “Ta-da!” The girl applauded. Bill emerged clutching a mountain of wrapped presents, immediately tripped over a balloon, and landed inside the piñata. “Molly,” he called, muffled, “I’ve discovered a flaw in the plan.” “Which one?” “The presents are heavier than our morals.” Before Molly could answer, the birthday boy approached. “Those are mine.” Bill crawled free. “Technically, they’re temporarily ours.” Molly sighed and returned the gifts. “We’re terrible thieves.” “Perhaps,” Bill said, accepting a cupcake, “but excellent party guests.” The girl handed Molly a wand. “Can you make the cake disappear?” Molly glanced at Bill. “Finally,” he whispered, “a heist with realistic objectives.”
