Molly spread the blueprints across the kitchen table, smoothing out the wrinkles with theatrical precision. "Behold," she said. "The Hendersons' backyard. Ground zero for Operation Birthday Bonanza." Bill leaned in, squinting. "Molly, this is a drawing of a square with the word 'GRASS' written in it." "It's a tactical overview." "You drew a sun in the corner. With sunglasses." "The sun is happy because we're about to be rich." She tapped the paper. "Now focus. The party starts at two. Twenty kids, minimum. You know what twenty kids means?" "Trauma?" "Presents, Bill. Mountains of presents. Action figures. Building blocks. Those little ponies with the rainbow hair that sell for a fortune online." Bill crossed his arms. "I'm not stealing toys from a child." "We're not stealing from a child. We're stealing from twenty children. It's a volume business." "That's somehow worse." "It's economies of scale." Molly pulled out a clown costume from a duffel bag and tossed it at him. "Put this on. You're the entertainment." Bill held up the costume, horrified. "Why am I the clown?" "Because I'm the magician, and the magician needs an assistant who can carry a sack." "I have a degree in mechanical engineering." "And yet here we are." She snapped the suspenders against his chest. "While I dazzle the parents with card tricks, you'll be loading the loot into a balloon-animal bag. Nobody suspects a clown holding balloons." "Everybody suspects a clown. Clowns are inherently suspicious." "Which is the genius of it. They'll be too scared to look closely." Molly slipped a pack of cards into her sleeve. "We're in, we're out, we're gone before the cake is cut." Bill sighed, stepping into the costume. "And how exactly do we get past the parents?" "Simple. I distract them with my world-famous disappearing dove." "You don't have a dove." "That's the trick. It already disappeared." She grinned. "Now, the presents. Where do people put presents at a kid's party?" "On a table. Usually by the door." "Exactly. Right next to the exit. It's like they're begging us." She zipped up the bag. "We waltz in, you honk a few times, I pull a quarter out of a kid's ear, and we leave with three hundred dollars of merchandise." Bill adjusted his oversized shoes, nearly tipping over. "What if a kid recognizes their own gift?" "Then you give them a balloon shaped like a dog." "I don't know how to make a balloon dog." "Make a balloon snake. It's just a balloon." Bill stared at his reflection in the toaster, defeated. "I never thought my life would come to this. A grown man in a clown wig, robbing toddlers." Molly clapped him on the shoulder. "That's the spirit. Now remember the code word if things go sideways." "What's the code word?" "'Pizza.'" "That's the same word we used last time, and you ordered an actual pizza." "And it was delicious." She slung the bag over her shoulder. "Let's go ruin some childhoods."
