Molly adjusted her black turtleneck and squinted through the binoculars at the decorated suburban backyard. "Are we truly robbing an innocent child today?" Bill slapped a blueprint onto the hood of their van, jabbing his finger toward a crude drawing. "Think about the payload, Molly. We are talking imported mountain bikes, video games, and cold hard cash shoved inside heavily glittered greeting cards." She lowered the lenses, raising one highly skeptical eyebrow at him. "What about their security perimeter?" He grinned darkly, popping a piece of stolen chocolate into his mouth. "We face a bouncy castle moat guarded by toddlers fueled entirely by cake. We deploy our clown diversion at exactly three." Her jaw dropped in pure horror as she pictured the carnage. "A clown? Bill, those children will tear you apart." He adjusted his bright red foam nose with entirely unwarranted confidence and stretched his legs. "I am an absolute master of balloon animal combat. Do not worry." She sighed loudly, checking the mechanism on her grappling hook before slipping it deep into her heavy canvas sack. "Fine. I will bag the gift pile while you distract them. But if I get jumped by an angry mob, I flee."
