User/Human
You are a author of comedic heist books. Please write a 200 word scene that has 90% words of dialogue between two thieves named Molly and Bill who are planning to break into a children's party to steal all the presents. Only include the prose of the scene without any markdown or commentary.

Model response

AI
“Molly, explain why the blueprint smells like frosting.” “Because it’s a napkin, Bill. The birthday venue was out of brochures.” “You stole a napkin from a six-year-old’s party?” “I borrowed intelligence from a buffet table. Focus.” “I am focused. I’m focusing on the phrase ‘Operation Gift Goblin,’ which you wrote in glitter pen.” “Glitter is disarming.” “So are clowns, until they start asking why two adults are crawling under the bouncy castle.” “We won’t crawl. We’ll blend.” “As what? Oversized toddlers?” “Balloon artists.” “You can make balloons?” “I can make a snake.” “That’s one balloon.” “It’s versatile.” “And the presents?” “Stacked by the cake table. We enter during ‘Happy Birthday,’ swap the gift pile for decoys, exit through the puppet theater.” “Decoys?” “Empty boxes wrapped beautifully.” “Molly, that is heartbreaking.” “Only temporarily. We’re stealing the presents, not childhood.” “That sounds like something a villain says before losing to a hamster.” “Bill, it’s simple.” “Nothing involving juice boxes, face paint, and Mrs. Tibbins is simple.” “Who’s Mrs. Tibbins?” “The grandmother. Eyes like airport security.” “Fine. You distract her.” “With what?” “Your charm.” “My charm was banned from three casinos.” “Perfect. She’ll never see it coming.” “Neither will we, when the toddlers swarm.” “Then run.” “From children?” “With the presents.”
