"So we're really doing this?" Bill asked. "Robbing a six-year-old?" "Not robbing. Liberating," Molly said. "Those presents are practically begging to be stolen." "They're wrapped in unicorn paper, Molly." "Premium loot. Focus, Bill." "What's the plan?" "You're the entertainment. Bozo the Clown." "Absolutely not." "The costume's in the trunk." "I have dignity!" "You stole a kidney from a hospital last week." "That had dignity! Clowns are terrifying!" "Exactly. You'll distract the kids while I sweep the gift table." "And the parents?" "Cake. There's always cake. Parents swarm it like pigeons." "This is insane." "It's foolproof. What could a bunch of kindergartners possibly do?" "They bite, Molly. I've seen documentaries." "Wear the gloves." "And if someone recognizes us?" "From what? You'll be Bozo. I'll be the face-painting lady." "You can't paint faces!" "I'll paint something. A blob. They're children, Bill, their standards are low." "This feels morally questionable." "We robbed a children's hospital." "Stop bringing that up!" "Then commit. Honk the nose, juggle a little, and when I signal—" "What's the signal?" "I'll yell 'piñata.' Everyone goes berserk for piñatas." "And then?" "We grab the presents and run." Bill sighed. "I hate this job." "You said that about the orphanage too."
