Molly spread the birthday flyer across the dashboard of their rusted van. The flyer was laminated in glitter and poor parental decisions. PRINCESS SOPHIA'S SEVENTH BIRTHDAY EXTRAVAGANZA! it screamed. A mountain of wrapped presents loomed in the background of the photo. Bill leaned over, donut crumbs tumbling from his chin. "We are not robbing a seven-year-old," Bill said. "We are redistributing her unholy accumulation of plastic ponies," Molly said. "That's still a kid's birthday party. That's a new low, even for us." "We stole a piƱata full of dentures last week, Bill. Our bar is subterranean." Molly flipped the flyer over. On the back, someone had written a schedule in purple marker. Clown arrival, cake cutting, treasure hunt, nap time. She circled treasure hunt with a red pen that smelled like cherries. Bill watched her with the deep dread of a man who knew where this was going. "Okay, listen. Thirty kids means thirty gift bags, plus Sophia's actual presents. That's a haul." "That's also thirty witnesses, one of whom knows karate, according to the flyer." "Chloe's Karate Corner is just a fifteen minute demonstration. We can handle it." "She's seven and has a yellow belt, Molly. We lost a fight to a raccoon." The van smelled like old coffee and desperation. Outside, the suburban street was quiet except for a distant bounce house inflating with a wheeze. Molly had already acquired costumes from somewhere Bill did not want to ask about. Two oversized clown suits hung limply from the rearview mirror, staring at them with dead felt eyes. "Absolutely not," Bill said. "Last time you made me wear face paint, I had a rash for a month." "That rash built character. Look, we walk in, we blend in, we grab the present table during cake time. Nobody notices two extra clowns." "Everyone notices clowns, Molly. That's their whole terrifying deal." "We'll be funny clowns. Kid-friendly." Bill picked up one of the suits. It had squeaky shoes attached. He squeezed one and it let out a mournful honk that sounded exactly like his soul leaving his body. Across the street, a woman was setting up a banner that read HAPPY BIRTHDAY PRINCESS! Balloons escaped into the sky like they were trying to flee the scene in advance. "What's our exit strategy?" Bill asked. "We just waddle out with twenty boxes of LEGO?" "No. We have the wagon. The little red wagon. We put all the presents in the wagon and we pull it like we are part of the party games." "And when Princess Sophia notices her castle of toys is gone?" "We cry. Loudly. Like clowns do. Distraught clown tears." "Molly, kids can smell fear and dishonesty. And we reek of both." Molly stared at the mountain of presents across the street, her eyes wide and glittering. Bill stared at Molly. He sighed, reached for the clown nose, and put it on. It lit up. Neither of them spoke for a long time, which was rare. "Fine," Bill said. "But if we get taken down by a seven-year-old karate kid, I'm not splitting the loot." "Deal. And if we survive, you can keep the light-up nose. You look beautiful."
