Molly leaned over the blueprints spread across the dingy kitchen table, her eyes gleaming with mischief. Bill paced nearby, munching on a stale doughnut. "Okay, Bill, listen up," Molly whispered. "The party's at noon tomorrow—bouncy castle, clown, and a mountain of presents under that giant piñata. We sneak in as caterers. You distract the kids with balloon animals while I grab the gifts." "Balloon animals? Molly, I can barely tie my shoes! Last time I tried, it looked like a deflated giraffe humping a snake." "Fine, then you be the clown. Honk your nose, trip over your feet—kids love slapstick. I'll swipe the presents into our fake cake trolley." "But what if the parents spot us? One suspicious mom and we're toast!" "Relax, we'll wear disguises. You as Bozo the Balding Buffoon, me as Chef Ratatouille. And if things go south, we unleash the secret weapon: itching powder in the punch bowl. Chaos ensues, we bolt with the loot!" "Itching powder? That's genius! But Molly, what about the birthday kid? Stealing presents from a six-year-old? Feels low, even for us." "Bill, it's a heist, not a morality play. Think of the resale value—Barbies, Legos, that new video game console. We'll be rolling in cash!" Bill grinned. "Alright, partner. Let's rob those rugrats blind!"
