"So we're really doing this," Bill said. "Robbing a kid's birthday party." "Not robbing. Liberating gifts from spoiled children." "Molly, there's a bouncy castle." "Tactical advantage. Nobody suspects the bouncy castle." "How is a bouncy castle a tactical advantage?" "It's not. I just want to jump on it." "Focus. What's the plan?" "Simple. You distract the parents, I grab the loot pile." "How do I distract them?" "You're the entertainment. Bill the Magnificent." "I don't do magic." "You'll learn. Pull a rabbit out of something." "Out of where?" "Don't make it weird, Bill." "And the kids? There's like thirty of them." "Sugar-crashed by three o'clock. We strike during cake." "What if they cry?" "Then we've won. Crying children can't pursue." "This feels morally questionable." "It's a piñata, Bill. We're basically just an unscheduled piñata." "That doesn't make sense." "Neither does gifting a six-year-old a tablet. We're correcting society." "You're insane." "I'm aspirational. Now, the getaway car?" "An ice cream truck." "Brilliant. Nobody chases the ice cream truck." "Actually they chase it constantly." "Then drive faster. Are you in or out?" "...What's the cut?" "Sixty-forty." "Sixty me?" "Forty you. I'm doing the bouncy castle." "Deal."
