# The Birthday Caper Molly adjusted her fake mustache while studying the invitation. "So the Henderson kid's turning seven at the community center tomorrow." "Perfect," Bill said, twirling a plastic grappling hook. "Minimal security, maximum presents." "We'll need costumes," Molly continued. "I'm thinking clown. You're the balloon guy." "Why do I always get the weird one?" Bill complained, examining his oversized wig. "Because you pull off ridiculous better than anyone I know," she replied, checking her fake nose in the mirror. Bill spread a blueprint across the table, pointing at various locations. "The presents are stacked in the north corner during the pinata game." "That's our window," Molly said. "Fifteen minutes maximum." "What about the parents?" Bill asked nervously. "They'll be distracted by cake. Always are." She grinned mischievously. Bill stood up, suddenly serious. "This is wrong, you know. We're stealing from children." Molly patted his shoulder sympathetically. "I know. But look at the loot list. That limited edition action figure retails for eighty bucks." Bill's eyes widened. "For real?" "Absolutely. Now stop complaining and practice your balloon animals." They exchanged a knowing lookâtomorrow would be legendary.
