Molly adjusted her fake mustache in the dingy motel mirror, while Bill paced the room, clutching a crumpled blueprint of the suburban backyard. "Alright, Bill, listen up," Molly whispered, her voice muffled by the disguise. "The party's at noon. Kids'll be distracted by the clown— that's our window." Bill snorted, eyeing the map. "A clown? You're kidding. What if he juggles our getaway? Nah, we go in as caterers. 'Extra pizza delivery!' Bam, we're inside." Molly rolled her eyes. "Pizza? At a birthday bash? That's suspicious. Better as balloon artists. Inflate a few, stuff the presents in giant ones, float 'em out." "Float 'em? Molly, those things pop louder than my ex-wife's temper. We'll look like idiots chasing helium dreams. Stick to basics: I distract with magic tricks, you swipe the loot." "Magic? You can barely pull a rabbit out of a hat without it biting you! Fine, but if we get caught, I'm blaming your sleight of hand." Bill grinned. "Deal. Imagine the haul— bikes, toys, that giant teddy. We'll fence 'em for a fortune." "Just remember, no touching the cake. I draw the line at frosting felonies." They high-fived, laughing maniacally as the plan solidified.
