"The backyard perimeter is heavily fortified by strictly ruthless suburban mothers," Bill whispered. "It is an inflatable bouncy castle, you dangerously dramatic lunatic," Molly sighed. "Exactly. We breach during the main piƱata distraction. The oblivious toddlers will be totally blinded by extreme sugar greed. I loudly secure the patio, you grab every single brightly wrapped box," Bill grinned. "Are we genuinely stealing expensive luxury toys from completely innocent children?" Molly asked. "This is a highly lucrative operation. Did you assess the dimensions of that brand new Lego spaceship box?" Bill replied. "Fair point. What exactly will we do about the hired party clown?" Molly nodded. "He is merely an outside contractor. I paid him to secretly swallow his squeaker nose at three," Bill stated. "Sheer tactical genius. What is our designated extraction vehicle?" Molly laughed. "The neighborhood ice cream truck. We toss the gifts into the deep freezer, then smoothly escape playing a happily jingling melody," Bill smirked. "What if the birthday brat demands a valid receipt?" Molly groaned. "I flawlessly forged totally fake retail returns." "You definitely completely overthought this simple heist." "Professionalism prevents poor performance. Pick up your unicorn mask and let us utterly ruin this seventh birthday."
