Bill stared at the blueprint spread across the hood of their rusty getaway van. He scratched his chin, leaving a long dark smear of motor grease on his square jawline. The stakes were higher than usual. "Are you telling me the main vault is inside a bouncy castle?" Molly adjusted her highly reflective mirrored sunglasses and pointed a perfectly manicured finger at a hastily drawn red circle on the heavily crinkled map. "It is a formidable fortress of inflated vinyl. The target is a huge pile of brightly wrapped loot. It is heavily guarded by a dozen frosting covered kids." Bill shook his massive bald head slowly, vividly recalling a terrible past birthday gig. "Those monsters are vicious when they eat cake. I still have a shin scar." She tapped a thick green marker repeatedly against the faded van hood. "Exactly. We need absolute precision. We strike right when the clown arrives. The adults will be completely distracted by the dumb balloon animals." He actually shivered, crossing both of his thick muscular arms firmly over his chest. "I am truly terrified of clowns." She rolled her eyes toward the sky and slapped his broad left shoulder. "Suck it up. Once the clown pulls out the magic handkerchief, you slip through the patio door and secure the perimeter. I will infiltrate the ball pit." Bill squinted hard at the colorful diagram, trying miserably to properly visualize the stealthy escape route. The target yard was completely fenced around all the outer edges. "How are you getting out carrying fifty shiny toy boxes?" She smiled widely, proudly revealing perfectly white teeth gleaming in sunlight. "I bought a giant laundry basket. We tell the parents we are a recycling service hired to collect the discarded wrapping paper. We sweep up the paper, and scoop the unopened gifts underneath." Bill chuckled softly. "That is brilliant. What about the actual birthday boy?" Molly unrolled yet another much smaller floor plan specifically showing the interior of the main house. "Timmy gets a distraction. I bribed his brother to release three hamsters into the kitchen. The ensuing chaos will give us exactly four minutes. Did you bring the hook?" He reached deep into the cluttered back seat and produced a very dangerous piece of coiled black steel. "Why do we need a grappling hook for a backyard?" She extended her arm and pointed her finger directly toward his nose. "To scale the wooden garden trellis if the grandmother spots us. She is a retired gym teacher." Bill nodded in agreement, carefully placing the heavy metal hook right back inside the vehicle. "Alright. I will go grab the rubber duck masks." Molly groaned significantly louder than she had safely intended. "No masks. We wear polo shirts and khakis to blend in with the suburban dads." He instantly let out a long defeated sigh while sadly glancing down at his ample stomach. "But I look terrible in tight khaki pants." Molly patted him gently on the back to provide encouragement.
