"Right, so the target is a seven-year-old," Molly said. "Say it louder, why don't you." "It's a bouncy castle, Bill, not Fort Knox." "That bouncy castle has a *perimeter*." "It has a deflated corner and a sign that says NO SHOES." "I'm just saying, we go in through the garden gate, we get the presents, we're out before the cake." "Before the cake?" "Before the cake." "Bill, we're not leaving before the cake." "That's not—Molly, that's not how a heist works." "It's a *victoria sponge*. Denise made it. Denise has won things." "You know Denise?" "Denise is my cousin." "Your cousin is hosting the party we are robbing?" "Which is how I know there's a Nintendo in the pile. Wrapped in penguins." "So you're on the guest list." "I'm on the guest list, I brought a gift bag, and I'm doing the pass-the-parcel music." "Then what do you need me for?" "You're the muscle." "Against who? Toddlers?" "Against Gary." "Who's Gary?" "Gary's the dad. Gary does CrossFit and he *watches* the present table." "So distract Gary." "That's your job. Ask him about his deadlift." "And then?" "And then he'll talk for forty minutes and I'll be in the car with a Nintendo and two slices of sponge." "...Three slices." "Don't be greedy, Bill."
