Molly pressed her back against the garden fence, clutching a clipboard like she was coordinating a military operation rather than robbing a six year old's birthday party. "The bouncy castle is our biggest obstacle," she whispered, sketching a rough diagram with her pen. "How is a bouncy castle an obstacle?" Bill asked. "Because you'll want to go on it. I know you, Bill." Bill opened his mouth to object, then closed it again. She had a point. "The presents are stacked by the gazebo," Molly continued, tapping her clipboard. "We go in during musical chairs. Everyone watches musical chairs." "What about the clown?" "What about him?" "He's been staring at me for ten minutes." Molly glanced over the fence. The clown was indeed staring directly at Bill with an expression of profound suspicion. "Clowns always look like that," she said. "That one has a walkie talkie." Molly looked again. He absolutely did. "Okay, new plan," she said. "Run away?" "Run away," she confirmed. They both sprinted down the street, Bill somehow still managing to glance longingly back at the bouncy castle as the clown calmly radioed in their description.
