Model response

Molly adjusted her fake mustache and peered through the hedge. A bouncy castle wobbled beside a mountain of gift-wrapped treasure, guarded only by parents staring at their phones. "You're the clown," she whispered. Bill looked down at the enormous red shoes. "Why me?" "The real clown is tied up in the van, and you fit his pants." "Children can smell fear." Bill squeaked forward one step. "They can smell balloon animals. Make one." "I only know how to make a sausage." "Then make a sausage with confidence." Molly checked her watch. "At two, I'll yell that the pizza's here. The kids stampede, you bag the presents." "This is the lowest we've ever stooped." "Remember the retirement home bingo night?" "We agreed never to speak of that." Bill winced beneath his rainbow wig. "And if a kid catches me?" "Honk your nose and say it's part of the show." Just then a tiny girl in a tiara materialized beside them, arms crossed, radiating suspicion. "You're not Giggles," she said. Bill swallowed, greasepaint sweating. Molly slowly reached for the emergency cupcake she'd brought as a bribe. "Nobody's Giggles," he whispered, "after tonight."
