Molly adjusted her oversized clown wig and peered through the hedge at the bouncing castle. “Bill, if you eat one more miniature sausage roll, I swear I’ll use your stomach as a getaway balloon.” “Relax,” Bill muttered, licking crumbs from his fake mustache. “We blend in. Who suspects two clowns at a kiddie party?” “Everyone with eyes. You’re wearing the bow tie with actual mice in it.” “They’re festive! Look, we hit the gift table at peak musical chairs. I create a diversion with my patented whoopee cushion symphony—” “Which every adult within fifty yards will instantly trace to the giant man in the polka-dot suit, genius.” “Then you swoop in like a glittery ninja, shove the presents in the piñata sack, and we’re out before they finish ‘Happy Birthday.’” Molly sighed. “If we get recognized by one sugar-high six-year-old, I’m selling you to the balloon animal guy.” “Fair. Just don’t forget the cake. I’ve always wanted to abseil down a bouncy castle with a stolen SpongeBob.” “You’re a terrible influence on children.” “I prefer ‘aspirational felon.’ Now hand me that squirting flower. Time to ruin some tiny dreams.”
