"Okay, so we go in through the bouncy castle," said Molly. "Through the bouncy castle." "Through the bouncy castle." "Molly, we can't go through the bouncy castle." "Why not?" "Because we'll be bouncing." "We'll be bouncing with purpose, Bill." "Right. And the clown?" "I've accounted for the clown." "How?" "I've hired a second clown." "To distract the first clown?" "Clowns hate each other. It's a known fact." "Where did you learn that?" "Clown school." "You went to clown school?" "Briefly. I got expelled." "For what?" "Insufficient whimsy. Now focus. The presents are stacked by the gift table near the piƱata." "We grab the presents and then what?" "We walk out the front door." "Just walk out." "Dressed as the entertainment." "We're not the entertainment." "We will be once I do my balloon animals." "Can you make balloon animals?" "I can make one." "Which one?" "A long one." Bill stared at her. Molly stared back, completely serious. "Okay," he said finally. "I'm in."
