Molly adjusted her oversized clown wig and peered through the hedge at the bouncing castle. "Bill, this is insane. We're stealing from children? What are we, heartless?" "Heartless? Nah, we're entrepreneurs," Bill whispered, tugging at his too-tight superhero cape. "Those presents are worth a fortune on the black market. Think of it as... redistributing birthday joy." "Redistributing? You're calling it that now?" Molly rolled her eyes. "Last week it was 'liberating surplus goods.' Face it, we're about to become the world's most hated piƱata punchers." Bill grinned. "Look, we slip in during musical chairs, grab the gifts while they're distracted by cake, and we're out before the parents notice. Easy peasy, lemon squeezey." "Easy? There's a bouncy castle full of sugar-crazed gremlins in there!" Molly hissed. "One wrong move and we'll be buried under a mountain of screaming kids demanding we sing 'Happy Birthday' at gunpoint." "Gunpoint? They're six, Mol. Worst they got is water pistols and poor aim." Bill checked his fake mustache. "Besides, I brought the emergency lollipops. We'll bribe our way out if needed." Molly sighed. "Fine. But if this ends with us on a registry for 'scaring toddlers,' I'm blaming your bright ideas."
