The seasoned thieves reviewed their notes one last time before embarking on the mission. Molly and Bill huddled in the back of their nondescript van staring at a hand-drawn map of the birthday party layout. Colorful party hats and streamers decorated the nearby house and distant giggles could be heard. Molly traced a path with her finger as Bill nervously chewed his lip. "Bill this children's party is our target. All those presents in one place," said Molly. "Molly are you serious? Stealing from kids?" replied Bill. "Dead serious. We enter as hired clowns. Create chaos with bad jokes," she explained. "I hate this. What if we get recognized by a parent?" he asked. "Wear the masks. I'll handle the sack. You watch the door," Molly insisted. "Fine but if a kid cries I'm done," Bill warned. "No crying. We'll be quick like ninja clowns," she reassured him. "Ninja clowns? That's the stupidest thing I've heard," he scoffed. "It's brilliant. Now let's go over the escape route. We'll use the bouncy castle for our getaway," Molly concluded with a smile. Bill sighed. "This better work Molly or we're finished." They packed their bags with fake noses whoopee cushions and other tools for their comedic caper.
