Model response

AI
Molly slapped the blueprint onto the table. "Okay, Bill, the party starts at two. The piƱata breaks at two-thirty. We hit at two-thirty-one." "Why then?" "Because every child will be blinded by candy and rage." "Beautiful. What's my cover?" "You're the clown." "I hate clowns." "Nobody likes clowns, Bill. That's why nobody will look at you." "And you?" "I'm the bouncy castle inspector." "That's not a real job." "Neither is clown, according to your mother." "Leave my mother out of this. How do we carry forty presents?" "Balloon animals. We hide the gifts inside a giant balloon giraffe." "I can only make dachshunds." "Then it's a very long dachshund. Nobody questions a dachshund." "What if a kid catches us?" "Then we cry louder. Never out-cry a professional." "What's the escape route?" "Ice cream truck. Parked outside, engine running." "Whose truck is it?" "Ours now. It plays 'Greensleeves' whenever we speed." "Molly, that's the most obvious getaway vehicle in history." "Exactly. Who chases a jingle?" Bill nodded slowly. "Fair. Dessert?" "Cake on the way out. Heist rule number one." "Never leave without cake." "Bill, I'm so proud."
