Behind the bouncy castle, Molly and Bill crouched in the shrubbery, whispering and plotting. "I can't believe we're robbing a children's party, Bill; even I have standards." "Relax, Molly, we're liberating the presents from capitalist toddlers drunk on frosting." "Those toddlers are four, they don't even know what capitalism is." "Exactly, their ignorance is our pension plan." "Walk me through it again before my conscience sobers up." "Simple; we infiltrate as budget clowns, perform, grab presents, vanish with tragic balloon finale." "Define budget clowns, because last time that meant me in a shower curtain." "This time you get a wig." "Oh brilliant, nothing says stealth like neon curls and honking shoes." "Distraction, Molly; parents film you, I forklift the gift table into my van." "That's not how forklifts or physics work." "Fine, I waddle out with three gift bags and a convincing limp." "What about security, you know, the sugar‑crazed horde guarding the piñata?" "We weaponize the piñata; I shout Free candy outside, they abandon their posts." "And if a child cries?" "We leave one present, obviously; we're thieves, Molly, not complete monsters." "Make it the noisy drum set, that'll punish the real culprits." "You are terrifyingly efficient, Bill, tonight."
