Molly and Bill crouched behind a cluster of inflatable birthday decorations, their eyes fixed on the bustling children's party. "So, what's the plan, genius?" Molly whispered, nudging Bill with her elbow. Bill grinned, his eyes gleaming with mischief. "Simple. We blend in with the crowd, snatch the presents when no one's looking, and make our escape." Molly raised an eyebrow. "Blend in? Have you seen us? We stick out like sore thumbs at a hand model convention." "Don't worry," Bill reassured her. "I've got a foolproof disguise." He pulled out two colorful party hats and handed one to Molly. She sighed, putting on the hat. "This better work, or we'll be the laughingstock of the criminal underworld." As they approached the party, Bill said, "Act natural. We're just here to celebrate little Timmy's big day." Molly scoffed. "Timmy? I thought it was Sarah's party." Bill shrugged. "Does it matter? Just smile and wave." They mingled with the guests, slowly making their way towards the towering pile of gifts. Molly leaned in close to Bill and whispered, "Now?" He nodded, a wicked grin spreading across his face. "On my mark. Ready? Set... thief!"
