Molly spread the blueprint across the table, jabbing a finger at a crude drawing of a bounce house. "So we go in through the ventilation shaft," Bill said, squinting. "Bill, it's a bounce house. There's no ventilation shaft." "Every heist needs a ventilation shaft, Molly. It's tradition." She rubbed her temples. "We're stealing birthday presents from six-year-olds. There is no tradition." "Fine. What's your genius plan then?" "We dress as clowns, blend into the party, and swipe the gift table when nobody's looking." Bill's eyes lit up. "Clowns! I've always wanted to be a clown." "This isn't about your childhood dreams, Bill." "Everything's about childhood dreams. That's literally the theme of the party." Molly groaned. "Just don't do the balloon animals. Last time you traumatized a toddler." "That giraffe was structurally sound!" "It looked like a snake having an existential crisis." "Artistic interpretation." She grabbed her bag of red noses and wigs. "Just grab the presents, Bill. Skip the performance." "No promises." He grinned, pulling on a rainbow wig. "This is either going to be the greatest heist of our careers, or we're getting arrested by a birthday clown named Sparkles." "Probably both," Molly muttered, heading for the door.
