"So let me get this straight," Bill said, leaning forward. "You want to steal birthday presents from a seven-year-old." "Not just any seven-year-old," Molly replied. "Tiffany Warbucks. Her dad's a tech billionaire. We're talking iPads, drones, probably a pony in a box." "A pony in a box." "I don't know their wrapping situation, Bill. Focus." "Right, sorry. How do we get in?" "The party's at Chuck E. Cheese. I bought two adult mascot costumes off a guy named Derek on Craigslist." "That raises several concerns." "We go in dressed as characters, load the presents into garbage bags, and walk right out the service entrance." "And nobody stops two giant mice carrying garbage bags full of children's gifts?" "We're rats, Bill. Chuck E. Cheese is a rat." "Oh, that changes everything." "The parents will be on their fourth glass of wine by two o'clock. They won't notice anything until the cake comes out." "What if a kid grabs my leg and starts crying?" "Shake them off gently. We're criminals, not monsters." "I really thought retirement would look different." "You'll retire when we fence Tiffany's pony. Now put on your rat head."
