Molly and Bill sat in their rundown van, parked across the street from the extravagant mansion where the children's party was in full swing. The sound of laughter and music filled the air, mingling with the aroma of cake and cotton candy. "Alright, Bill, here's the plan," Molly began, her eyes fixed on the grand entrance. "You'll go in through the back, dressed as a clown. That way, you'll blend in with the entertainment." Bill raised an eyebrow. "A clown? Really? Do I have to?" Molly shot him a stern look. "Yes, you have to. It's the perfect cover. While you're distracting the kids with your balloon animals and terrible jokes, I'll sneak in through the front, posing as a party planner." Bill sighed, resigned to his fate. "Fine, but I'm not wearing those ridiculous oversized shoes." "Deal," Molly agreed. "Now, once we're inside, we'll locate the gift table. You keep the kids and parents occupied while I quietly slip the presents into our bags." Bill nodded, a mischievous glint in his eye. "And then, we'll make our escape, leaving behind a bunch of disappointed rich kids and a mystery that'll baffle the police." Molly smirked. "Exactly. It's the perfect crime. No one suspects a thing at a children's party." As they prepared to exit the van, Bill paused. "Wait, what if someone recognizes us?" Molly laughed. "Don't worry, I've got that covered. We'll be wearing disguises so good, even our own mothers wouldn't know us." Bill looked skeptical. "I don't know, Molly. This seems risky. What if we get caught?" Molly placed a reassuring hand on his shoulder. "Trust me, Bill. We've pulled off heists far more dangerous than this. Plus, think of all the expensive gadgets and toys we'll be able to fence. It'll be like Christmas came early for us." Bill took a deep breath and nodded. "Alright, let's do this. But if I end up with a bunch of crying kids hanging off my clown suit, I'm blaming you." Molly grinned. "Don't worry, I'll save you from the tiny monsters. Now, let's go over the signal. If anything goes wrong, we'll use the code phrase 'The cake is a lie.' Got it?" Bill chuckled. "The cake is a lie. Got it. You know, sometimes I think you're more of a kid than the actual children at these parties." Molly shrugged. "What can I say? I've got a youthful spirit. Now, let's get our bags and start this show. We've got presents to steal and a reputation to uphold as the most notorious party crashers in town." With a shared laugh and a determined sparkle in their eyes, Molly and Bill stepped out of the van, ready to pull off the most daring and unconventional heist of their careers.
