Molly adjusted her ridiculous clown wig in the rearview mirror while Bill slouched in the passenger seat, fiddling with a whoopee cushion like it was a detonator. “Okay, genius,” she said, “run it by me again. Why are we robbing a six-year-old’s birthday party?” “Because little Timmy’s uncle is a diamond smuggler,” Bill whispered, eyes darting like the presents might overhear. “He’s hiding the goods inside those gift boxes. We hit the piñata, we hit the motherlode.” Molly snorted. “We’re not hitting the piñata, Bill. We’re not traumatizing children for sparkly rocks.” “Fine, fine. We blend in. I’ll be the balloon guy. You’re the face painter. We work the room, swap the real presents with identical-looking bags of socks, and—” “Socks?” Molly interrupted, turning to stare at him. “You want to replace diamonds with socks?” “High-quality socks. Wool blend. Very convincing.” “I’m going to murder you in front of the bounce house.” Bill grinned. “See? Method acting. Just channel that energy into being a disgruntled children’s entertainer. It’s perfect cover.” Molly rubbed her temples. “How do we even get inside? There’s a bouncer. A literal bouncer dressed as a dinosaur.” “We tell him we’re the surprise entertainment. I’ve got a kazoo and everything.” “A kazoo. Wonderful. The great heist of 2024, executed with a kazoo and some argyle socks.” “Don’t underestimate the kazoo, Mol. It’s got range.” She leaned back, sighing. “What about the parents? They’re going to notice two weirdos stuffing their kids’ presents into a trash bag.” “We’re not using a trash bag. We’re using a brightly colored ‘Lost and Found’ box. Kids lose stuff all the time. We’ll look helpful.” Molly gave him a long look. “You’ve thought about this way too much.” “I made diagrams. On napkins. From three different Chuck E. Cheese locations.” “You’re an actual lunatic.” Bill shrugged happily. “Lunatics get results. Remember the Great Easter Egg Fiasco of ’19?” “I still have chocolate in places chocolate should never be, thanks to that.” “Exactly. So when the lights go down for the cake song—” “There are no lights going down, Bill. It’s two o’clock in the afternoon.” “Then we create dramatic lighting. I brought a smoke machine. Small one. Disney approved.” Molly closed her eyes. “We are going to prison. And not even cool prison. The kind with arts and crafts.” “Think positive. We pull this off, we retire to that beach we talked about. You can write your memoirs. I’ll sell socks.” “Diamond socks,” she muttered. “See? You’re getting into the spirit.” Molly checked her watch. “Fine. We go in, we blend, we swap. But if a single child cries, I’m feeding you to the dinosaur bouncer.” Bill clutched his whoopee cushion to his chest like a shield. “Fair. Now help me practice my silly voice.” “No.” “Please? I need feedback on my ‘golly gee’ delivery.” Molly stared at him for five full seconds. “Golly gee, I’m going to kill you.” “Perfect!” Bill cheered. “Now we’re ready.”
