# The Birthday Caper Molly crouched behind the inflatable bounce house, adjusting her fake mustache. Bill appeared beside her, clutching a forged invitation. "So you'll go in through the kitchen entrance?" she whispered. "Right, grab the presents from the gift table while everyone's distracted by the piƱata," Bill confirmed, checking his watch nervously. "What if someone recognizes us?" "We're wearing clown costumes, Molly. Nobody recognizes clowns." She had a point. Molly straightened her oversized bow tie and surveyed the backyard. Six-year-olds ran everywhere like tiny drunk people. A DJ played something called "Llama Song" on repeat. "The good stuff's definitely in the garage, yeah?" Bill asked. "Three Xbox boxes, two dolls, and what looks like a real hoverboard." Bill whistled low. "This kid's parents are loaded." "One small problem though," Molly said, pointing at the gate. A German Shepherd the size of a small bear was now sniffing the air in their direction. "Run?" Bill suggested. "Definitely run," Molly agreed. They bolted toward the fence as the dog charged, their ridiculous oversized shoes slapping against the pavement.
