Molly cracked her knuckles and grinned at Bill across the van. "So we're really doing this? Robbing a six-year-old's birthday party?" "Don't say it like that. We're liberating presents from their capitalist prison." "Bill, there's going to be a bounce house." "Which provides excellent cover! Nobody suspects thieves in a bounce house." "You're banned from three Chuck E. Cheeses. How is this different?" "Those were misunderstandings. And I was never convicted." "Because they were Chuck E. Cheeses! The police laughed at you!" "Look, Molly, that jewelry store job went sideways. We need this score." "It's Fisher-Price toys and maybe a bicycle!" "A bicycle we can fence. And have you seen what American Girl dolls go for?" "You've researched this?" "I'm a professional." "We're about to case a house with balloon animals outside." "Those balloons are the perfect distraction. When the clown starts making the giraffe, we strike." "I hate you so much right now." "You'll thank me when we're splitting the goods." "If we get caught by a birthday mom, I'm telling her everything." "Deal. Now grab the empty diaper box. That's our cover."
