Molly adjusted her fake mustache in the rearview mirror of their beat-up van parked two blocks from the birthday bash. “Bill, I still can’t believe we’re doing this. We’re about to crash a kiddie party like it’s the Crown Jewels.” Bill grinned, peeling the wrapper off a stolen Fun Size Snickers. “Hey, those presents are worth more than gold to the little gremlins. We grab the table full of wrapped boxes, we’re set for Christmas. You got the clown noses?” “Two red ones and a whoopee cushion for distraction,” Molly said, stuffing them into her overalls. “But listen, genius, what’s our cover story when the soccer moms ask why we’re not wearing birthday hats?” “We’re the entertainment! I’m Bongo the Magnificent, master balloon animal sculptor. You’re my lovely assistant, Sparkles McGee. We waltz in, I make a giraffe, you slip the gifts into the big sack disguised as a piñata. Easy peasy, lemon squeezy.” Molly snorted. “Sparkles McGee? That’s the best you could do? Last time you called me that I ended up explaining to a cop why I had a sack full of silverware.” “This is different,” Bill insisted, checking the fake clipboard. “No silverware, just Barbies and Lego sets. High demand on the black market. My guy Frankie says he can flip a talking unicorn for fifty bucks easy.” “Fifty bucks? We’re risking felony fun time for fifty bucks? Bill, there’s gotta be a hundred presents in there. Little Timmy’s parents rented a bouncy castle. That means rich people. Rich people give rich gifts.” “Fine, fine, we aim for the big shiny ones,” Bill conceded. “But we can’t just shove everything in the bag. We gotta be selective. I’ll create a diversion by ‘accidentally’ releasing the helium balloons. Chaos ensues, kids scream, parents chase floating Mylar. Meanwhile you swap the present table with our decoy box full of newspaper.” Molly rolled her eyes. “Newspaper? They’ll notice when little Emily opens her gift and finds yesterday’s sports section. We need better decoys. I brought some old socks and a broken toaster. Looks heavy, feels disappointing, classic misdirection.” “You beautiful criminal,” Bill said with genuine admiration. “Okay, timeline. We hit at peak cake time, around two-fifteen. I start the balloon animals, you work the crowd with face paint. When the birthday boy blows out the candles, that’s our window. Everybody’s singing, nobody’s watching the gift table.” “What if they sing Happy Birthday to You off-key? That song always makes me emotional, Bill. I might hesitate.” “Don’t you dare get soft on me, Sparkles. Those presents are funding our retirement in Boca. Think of the beach, not the sobbing children. We’ll leave one crappy gift so they don’t feel completely robbed. A nice participation trophy or something.” Molly checked her watch. “It’s showtime in six minutes. You ready to ruin the happiest day of some six-year-old’s life?” Bill pulled on his oversized clown shoes. “Born ready. Just promise me one thing.” “What?” “After we fence the haul, we never speak of this again. Especially not to my mother.” Molly laughed, adjusting her rainbow wig. “Deal. Let’s go steal some joy, Bongo.”
