"Right, Bill, here's the plan. We slip in through the bouncy castle vents," Molly whispered, tapping a crumpled map. "The bouncy castle has vents?" "Every bouncy castle has vents, Bill. Focus. Once inside, we grab the presents from under the tinsel tree." "Which ones? There are forty boxes." "The shiny ones. Big bows. Expensive-looking." "What if they're just wrapped in newspaper?" "Then we steal the newspaper too. Obviously." "Molly, the little boy in the clown hat looked at me funny earlier." "He's six, Bill. Ignore him. Now, the getaway. We use the ice cream van." "We don't have an ice cream van." "We have one now. I borrowed it from Doug." "Doug's the one who's still wearing the balloon animal, isn't he?" "Focus, Bill. Hats on. Masks on. Remember, nobody sees a bandit in a party hat." "They saw the last one. He was dancing with a pinata."
