"So we're really doing this?" Bill asked. "Robbing a six-year-old?" "His name is Tristan, and he's turning seven," Molly said. "Oh, well, that changes everything." "Look, the kid's parents are loaded. You see the gift table? PlayStations, drones, probably bonds." "Bonds? At a birthday party?" "Rich people are weird, Bill." "And the plan?" "You distract them. Magic show. I sweep the loot into the van." "I don't know magic, Molly." "You pulled a quarter out of my nephew's ear last Christmas." "That was an accident! It fell out of my sleeve!" "Perfect. Improvise." "What if they ask for balloon animals?" "Then make a balloon animal." "I can only make snakes." "A snake is an animal, Bill." "It's a deflated balloon with a sad face drawn on it." "Kids love that postmodern stuff." "And if it goes wrong?" "It won't go wrong." "You said that about the bakery." "The bakery had a guard dog!" "It had a poodle named Cupcake!" "Cupcake bit you, Bill." "Cupcake drew blood, Molly!" "Focus. Clown costume's in the bag. Put the nose on." "This nose smells like cheese." "That's the previous clown." "What happened to the previous clown?" "Don't ask questions you don't want answered. Now go juggle."
