"So we're really doing this?" Molly asked. "Stealing from children? Absolutely." "Bill, that's monstrous." "They're rich children, Molly. Their presents are basically tiny investments." "How do we get in?" "I've got two clown costumes." "You hate clowns." "I despise clowns. But sacrifices must be made for art." "This isn't art. This is grand theft toy." "Same energy," Bill said. "Now, the party starts at two. Cake at three. Present-opening at four." "And we strike when?" "During musical chairs. Pure chaos. Nobody watches the gift table when there's a chair shortage." "What about the parents?" "Distracted. Filming everything. Half of them will be drunk on box wine." "At a children's party?" "You've clearly never met suburban parents." Molly frowned. "What's our exit?" "The bouncy castle out back. We toss the bags over the fence, slide down the inflatable slide, gone in sixty seconds." "That's ridiculous." "That's genius." "What if a kid recognizes us?" "Children can't testify, Molly. They still believe in the tooth fairy." "You're a terrible person." "I'm a professional," Bill corrected. "Now put on the wig." "It smells like sadness." "That's the smell of money." "Fine," Molly sighed. "But I'm keeping the dinosaur one." "Obviously. That dinosaur's mine."
