Molly adjusted her oversized clown wig and squinted at the crudely drawn map of Little Timmy’s fifth birthday extravaganza. “Okay, Bill, we hit the party at peak present-stacking time. Right when they’ve got that pile of shiny boxes under the balloon arch like a dragon’s hoard. You still got the kazoo?” Bill patted the pocket of his rented purple dinosaur costume. “Right here, Mol. I’m gonna honk it three times. That’s the signal. You swoop in from the bouncy castle, I create a diversion by pretending I sat on the cake. Classic.” “You always want to sit on the cake,” Molly said, rolling her eyes. “Last time you sat on a wedding cake we almost got caught because you kept moaning about how moist it was.” “That was a compliment to the bride’s mother,” Bill protested. “Look, we can’t just walk in and start stuffing presents down my dinosaur tail. These are parents, Mol. They notice when a six-foot purple reptile starts juggling Barbie Dreamhouses.” Molly tapped the map. “That’s why I’m going as Princess Sparklebottom. I’ll tell them I’m the hired entertainment. While I’m leading the sing-along, you roll the wagon in disguised as the piñata delivery guy. We load every gift, then I yell that the real Princess Sparklebottom is stuck in traffic. Chaos. We vanish.” Bill grinned, showing the gap where his front tooth used to be. “I love it when you go full princess. Remember the tiara from the museum job? You wore that for three weeks. Kept calling me ‘my loyal peasant.’” “You looked good in sackcloth,” she shot back. “Focus. The birthday boy’s getting a remote-control monster truck. That’s worth at least two hundred on the fence. Plus there’s a junior microscope set, some limited-edition stuffed unicorn, and what looks like a solid gold ‘World’s Best Nana’ necklace that I’m pretty sure is actually real.” Bill whistled. “Nana’s slumming it at a kid’s party? Bold. What about exit strategy? We can’t exactly peel out in the dinosaur-mobile. Neighbors will talk.” Molly smirked. “That’s the beauty part. We stash the real getaway van behind the bounce house. You release the helium balloons on our way out. Two hundred balloons, Bill. The whole street’s gonna be watching sparkly latex float away while we drive off with every gift under the age of six. They’ll think it’s part of the show.” “You beautiful, terrifying woman,” Bill said, clutching his foam belly. “What if the kids cry?” “Let them cry,” Molly replied with a theatrical shrug. “They’ll learn early that life is full of disappointing reptiles. Besides, I left a bag of off-brand lollipops in the van. We’re not monsters.” Bill checked his watch. “Party starts in forty minutes. You ready to ruin some childhoods, Princess?” Molly twirled an imaginary wand. “Born ready, peasant. Just remember: if anyone asks, the cake sat on you.” They bumped fists, the sound muffled by foam and sequins, then waddled toward the minivan that would carry them to the scene of the most adorable crime in suburban history.
