Molly spread the blueprint across the table, jabbing her finger at a crudely drawn bounce house. "So we go in through the bounce house," she said. Bill stared at her. "Through it? Molly, it's a bounce house. Not a tunnel." "I know what it is, Bill. I'm saying we deflate it, crawl under the tarp, and pop up by the present table." "Or," Bill said, "we could just walk in the front door dressed as clowns. Nobody suspects clowns." "Everybody suspects clowns! That's literally the most suspicious thing you could wear to a seven-year-old's birthday party." "Fine. Magicians, then." "Bill, we are not debating costumes right now. Focus. There's forty presents on that table. Forty. We grab the bag, we're out in ninety seconds." "What about the piƱata?" "What about it?" "It's shaped like a treasure chest. Feels personal." Molly closed her eyes. "It is not a sign, Bill." "I'm just saying the universe has a sense of humor." "The universe," Molly said, gathering the blueprints, "is about to watch two grown adults steal Tonka trucks from toddlers. Get the mask." Bill grinned. "Clown or magician?" "Neither! Ski mask, like normal criminals!"
