Model response

AI
Behind the hedge, Molly and Bill crouched over a crumpled party invitation. "Bill, the plan's simple. We break into the kids' party at bouncy castle hour." "Why then?" "By four o'clock, every parent is three prosecco deep and staring at the inflatable shark. Nobody watches the gift table." "How many presents?" "Forty-three, stacked beside the cake. We take every last one." "Forty-three presents for one six-year-old? That's not a birthday. That's a hostage situation." "Stop being dramatic. You're going in as a clown." "Absolutely not. Clowns terrify me." "Clowns terrify everyone. That's why nobody looks at them." "What about security?" "Just one six-year-old named Tyler. He has a clipboard. We bribe him with cake." "That's a mini mob boss." "Relax. The birthday song drowns out everything. You sing loudest." "I sing like a dying goose." "Perfect. Nobody hears a goose over thirty screaming toddlers." "And the getaway?" "The ice cream van, parked out back. Engine running." "That van plays that horrible jingle whenever it moves." "Then you sing along. Loudest." "And if Tyler catches us?" "Hand him a balloon. Tell him the tooth fairy sent us." "Why would he believe that?" "Clowns have a union, Bill. Lying to children is in the contract."
