Molly peered over the crumpled map that was actually a crumpled juice-box coupon. Bill cracked his knuckles like a man who had never cracked a safe without laughing himself clumsy. “Molly, darling disaster,” Bill said, “we hit the birthday bash at cake time. Kids go crazy for frosting and we scoop every wrapped box while the clown juggles his dignity.” “Brilliant, Bill,” Molly replied, adjusting an imaginary monocle. “I’ll pose as the balloon lady. You dress as a retired pirate snapping photos. When the piñata drops we stuff the gifts into my comedy oversized purse.” Bill grinned wider than a jack-o’-lantern. “What if the little monsters notice us swiping their loot?” “We dazzle them with knock-knock jokes so terrible their parents usher us out with the presents for free,” Molly said. “I knock on your head, you say who’s there, I say Potato Thief, you say Potato Thief who, I say the one dragging your pile of robot dinosaurs out the fire exit.” “Perfect comedy armor,” Bill agreed. “And if the cops show?” “We claim it’s performance art about greed,” Molly whispered solemnly. “Then we run laughing into the sunset with enough Legos to build a getaway car.”
