Molly: “Okay, Bill, whisper. We’re not robbing Fort Knox, we’re robbing a balloon-themed birthday party.” Bill: “That’s still a fortress. Balloons are nature’s booby traps.” Molly: “Not if we treat them like harmless floating garnish.” Bill: “They pop like gossip.” Molly: “Focus. The presents are the prize, not the air.” Bill: “Speaking of air, did you bring the duct tape?” Molly: “I brought duct tape, a silent alarm squeaker, and the ability to act like we’re supposed to be here.” Bill: “Your ability is mostly suspicious blinking.” Molly: “I blink normally.” Bill: “You blink like you’re trying to remember a password.” Molly: “It’s called emotion management.” Bill: “That’s called fear.” Molly: “It’s called skill. Now, check the route. We go through the side gate, past the pinata, and—” Bill: “—and avoid the dog.” Molly: “We can negotiate.” Bill: “With the dog?” Molly: “Dogs love sincerity. I’ll offer him a coupon for belly rubs.” Bill: “Dogs don’t redeem coupons.” Molly: “Then I’ll offer him the coupon’s spirit.” Bill: “The spirit of belly rubs sounds like a ghost story.” Molly: “Exactly. He’ll be scared and we’ll be invisible.” Bill: “We’re never invisible. You once got stuck in a coat rack.” Molly: “It was a stretch goal. I call that ‘covert interior design.’” Bill: “Interior design should not involve kidnapping a hanger.” Molly: “Listen. Once inside, we find the present pile.” Bill: “And we steal all the presents.” Molly: “Yes. Every single one. Even the weird ones.” Bill: “There will be weird ones.” Molly: “There is always at least one stuffed animal that looks like it survived a haunted basement.” Bill: “That’s called ‘vintage.’” Molly: “That’s called ‘lawsuit.’” Bill: “How do you plan to grab them?” Molly: “We’ll use the gift bags.” Bill: “The gift bags are for guests.” Molly: “So? We’ll guest responsibly.” Bill: “You mean steal like guests.” Molly: “Precisely. Like we’re doing customer service.” Bill: “Customer service theft.” Molly: “You’ve never seen it. I’m very polite while stealing.” Bill: “You once said, ‘Thank you for your valuables’ while waving a hand.” Molly: “Because manners matter.” Bill: “Manners matter less when you’re holding scissors near someone’s fingers.” Molly: “Those were decorative scissors. For gift wrap.” Bill: “Decorative scissors that you used on a price tag.” Molly: “The price tag wanted to be removed. It was suffering.” Bill: “Suffering from capitalism.” Molly: “Now shut up and map the timing. When do we act?” Bill: “During the ‘clap for cake’ moment.” Molly: “Cake applause.” Bill: “Kids are distracted. Parents are filming. Everyone’s looking up.” Molly: “Perfect. Gravity does the rest.” Bill: “How do we get past the door without making noise?” Molly: “Quiet feet. Soft hands. And you—” Bill: “—and me?” Molly: “Stop stepping on the squeaky toy.” Bill: “It wasn’t squeaky when I found it.” Molly: “It has been squeaky since 2012.” Bill: “That’s just hearsay.” Molly: “Bill. It’s squeaking right now.” Bill: “No it isn’t.” Molly: “Then why did I just hear it squeak?” Bill: “Maybe the house is dreaming.” Molly: “Houses don’t dream, Bill. They creak. Now, costume.” Bill: “Your plan involves costumes?” Molly: “Of course. I’m going as a friendly magician.” Bill: “And I’m going as…?” Molly: “A birthday clown.” Bill: “I hate clowns.” Molly: “Everyone hates clowns. That’s why they work. People assume you’re harmless.” Bill: “Clowns are never harmless.” Molly: “Not you. You’re a clowns-with-a-plan clown.” Bill: “A plan that involves stealing from children.” Molly: “Technically, we’re borrowing their presents temporarily.” Bill: “Temporarily forever.” Molly: “Forever temporarily.” Bill: “Words don’t make it better.” Molly: “It makes it funnier.” Bill: “Okay, okay. You borrow, I carry. Where’s the container?” Molly: “In my backpack.” Bill: “Your backpack is already bulging.” Molly: “It’s just snacks.” Bill: “Your backpack smells like wrapping paper.” Molly: “Snacks come in many forms.” Bill: “That’s not how snacks work.” Molly: “Let’s do this. One last check: eye on the present pile, no heroics, no talking to parents, and—” Bill: “—and don’t touch the cake.” Molly: “I would never. Cake is bait.” Bill: “Then let’s be thieves with restraint.” Molly: “We’re thieves. We have restraint.” Bill: “You once ate a cupcake I was saving as evidence.” Molly: “It was destiny.” Bill: “Destiny tastes like sugar and guilt.” Molly: “Guilt is just sugar with feelings.” Bill: “Molly, please. The door.” Molly: “Quiet. Ready?” Bill: “Ready.” Molly: “Smile like you belong.” Bill: “I can’t smile that hard.” Molly: “You can. Think of something joyful.” Bill: “Like… not getting caught?” Molly: “Like stealing presents.” Bill: “That’s not joyful.” Molly: “It’s joyful for us. Now move.”
