Molly leaned against the van. "So we're really doing this?" "Twenty grand in gift cards alone," Bill said. "Rich kids, rich parents." "It's a birthday party for a seven-year-old." "Exactly. They won't suspect a thing." "Bill, there will be clowns." "We'll blend in." "How exactly do we blend in with clowns?" "Easy. We become clowns." Molly stared at him. "You're insane." "I already bought the costumes." "Of course you did." "Look, we get in during cake time. Everyone's distracted. We grab the present table, we're out in ninety seconds." "What if someone sees us?" "We're clowns! We'll juggle!" "You can't juggle." "I'll learn on YouTube." "This is the worst plan you've ever had." "Remember the casino job?" "Okay, second worst." "So you're in?" Molly sighed. "What's my clown name?" "Sparkles." "I hate you so much right now." "That's the spirit! Now help me inflate these balloon animals." "They're already inflated, Bill." "Oh. Right. Then we're ready." "We're going to jail." "Not if we juggle convincingly."
