Molly adjusted her oversized clown wig and squinted at the crudely drawn map on the diner napkin. “Bill, if you say ‘it’s just like the casino job’ one more time I’m going to shove this entire whoopee cushion down your throat.” Bill grinned around a mouthful of pancake. “Relax, Mol. It’s literally a bunch of six-year-olds. What are they gonna do, bite our ankles? We roll in, we roll out, we roll home with forty Barbie dream houses and a mountain of Pokémon cards.” “Those kids have the collective attention span of a goldfish on espresso,” Molly hissed. “One scream and we’re swarmed by soccer moms with fanny packs full of judgment. We need a plan that doesn’t end with us on the local news as ‘the idiots who made Timmy cry.’” “Which is why,” Bill said, tapping the napkin with his fork, “phase one: distraction. I dress as a six-foot-tall purple dinosaur. Kids lose their tiny minds, parents take videos instead of paying attention.” “You’re going to be Barney? You? The man who once cried during a bank heist because the teller was ‘too nice’?” “I prefer the term ‘method actor.’ Anyway, while they’re all singing the ‘I Love You’ song, you slip in the back as the stressed-out mom who forgot the goodie bags. Classic misdirection.” Molly rubbed her temples. “Fine. But if you start doing the dinosaur dance, I will abandon you and keep all the loot. Also, we’re not touching the birthday cake. Last time you stress-ate an entire sheet cake and spent three days regretting your life choices.” “Cake is off limits, noted. What about the piñata? That thing’s probably stuffed with cash and tiny bottles of hand sanitizer.” “Leave the piñata. I’m not getting clubbed by a blindfolded child with a plastic bat. We hit the gift table at the exact moment they start ‘Happy Birthday.’ That’s our window. Thirty seconds max.” Bill leaned in, eyes gleaming. “Then we rendezvous at the bouncy castle. I’ll have the van idling by the fence. We dump the presents in the back, peel off the costumes, and vanish like classy phantoms.” “Classy phantoms who stole toys from children,” Molly muttered. “We’re going to hell, Bill. A very brightly colored, balloon-filled hell.” “Hey, we’re not monsters. We’ll send them a postcard from the Cayman Islands. ‘Sorry about your Legos, love, the Clown and the Dinosaur.’” Molly sighed and snatched the last piece of bacon from his plate. “If this goes south, I’m telling the cops it was all your idea and that you made me wear the wig.” “Fair. Just don’t forget the most important part.” “Which is?” Bill winked. “We leave one present behind. That way they’ll think it was a really weird magician who got confused about his gig.” Molly stared at him for a long second, then shook her head with a reluctant smile. “You’re an absolute menace, you know that?” “Yeah,” Bill said cheerfully, “but I’m your menace. Now pass the syrup. Evil geniuses need carbs.”
