Molly leaned against the van. "So we're really doing this?" "Kids' birthday party, tons of presents, easy money." Bill adjusted his fake mustache. "I feel like we've hit a new low." "Low? This is genius! Security at a six-year-old's party? What are they gonna have, a bouncy castle guard?" "The parents will be there, Bill." "Drunk on mimosas and complaining about their mortgages. Trust me." Bill pulled out a deflated clown costume. "You're Giggles, I'm Sparkles." "I'm not wearing that." "Fine, you're Sparkles, I'm Giggles." "That's not better! Why are we clowns?" "Because nobody questions a clown at a party. It's science." "It's idiotic." "Remember the museum job? The yacht heist? This is just like those, except smaller victims and cheaper champagne." "Those victims could fight back." "Have you met a six-year-old? They're vicious!" Bill tossed her the costume. "Now hurry up. Party starts in twenty minutes." "I hate you." "You'll love me when we're splitting thousands in Lego sets." "We're not fencing Legos, Bill." "Not with that attitude."
