Molly: “Bill, remind me why we’re robbing a children’s party?” Bill: “Because the invitation said presents, cake, and a bouncy castle. That’s a retirement plan.” Molly: “We’re stealing gifts from children.” Bill: “Borrowing. Permanently. Besides, I made a list.” Molly: “You made a list?” Bill: “Crayons, toy dinosaurs, three boxes labeled ‘Best Aunt Ever,’ and one rectangle.” Molly: “Your moral compass is broken.” Bill: “It points toward valuables.” Molly: “What’s the plan?” Bill: “We enter disguised as entertainers.” Molly: “You can’t juggle.” Bill: “I can drop three objects simultaneously.” Molly: “That’s not juggling. That’s a cry for help.” Bill: “You’ll be the magician. I’ll be the rabbit.” Molly: “You’re six feet tall and allergic to wool.” Bill: “Then I’ll be a rabbit.” Molly: “How do we get past the parents?” Bill: “I’ll announce a game called ‘Pin the Tail on the Criminal.’” Molly: “And then?” Bill: “While everyone argues over the blindfold, we grab the presents.” Molly: “That is catastrophically stupid.” Bill: “Your better idea?” Molly: “We bring a gift, behave politely, and leave with our dignity.” Bill: “Dignity doesn’t fit in a sack.” Molly: “Neither does a conscience.” Bill: “Fine. We steal the cake.” Molly: “Finally, a crime with frosting.”
