"So we're really doing this?" Molly asked. "Robbing children?" "Not robbing children," Bill said. "Robbing presents. Big difference." "How is that different?" "The children don't pay for the presents. So technically, we're robbing the parents." "The parents who love their children." "Look, do you want to eat this month or not?" "I want to eat," Molly admitted. "I just don't want to make a six-year-old cry." "Then we wait until after the cake. They're too sugar-high to notice anything." "That's your plan? Sugar?" "That's half my plan. The other half is the bouncy castle." "What does the bouncy castle do?" "Distraction. Nobody watches the present table when there's a bouncy castle." "And how do we get in?" "I'm the magician. You're my assistant." "I'm not wearing a sequined leotard, Bill." "You'll wear what the act demands." "The act demands dignity." "The act demands sequins." "What if they ask you to do real magic?" "I pull a rabbit from a hat. I've practiced." "You have a rabbit?" "I have a hat. The rabbit's a work in progress." "This is going to fail spectacularly." "Probably," Bill agreed. "But think of the presents." "Fine," Molly sighed. "But I'm keeping the bouncy castle."
