“Bill, you’re joking. A children’s party? We’re not stealing candy from babies, we’re stealing from actual babies.” “Toddlers, Molly, and their presents are wrapped in shiny paper. Shiny paper means expensive. Think of the haul.” “I’m thinking of the screaming. There’ll be tiny humans everywhere, sticky fingers, snot bubbles—” “Exactly. Chaos is our friend. We’ll wear the mascot costumes, waddle in, and while the clown distracts them with balloon animals, we load the gifts into the fake bouncy castle.” “That’s a bounce house, genius, and how do we get a fake one through the door?” “Details. You handle the mom. Tell her you’re the hired magician’s assistant. I’ll be inside the T-Rex suit. Kids love T-Rexes.” “Kids also love biting. What if one chomps my ankle?” “Then you hop around screaming ‘rawr’ and they’ll think it’s part of the show. Meanwhile I’m vacuuming presents into the belly pouch.” “You’ve lost your mind. Fine. But if I get recognized by some PTA harpy, I’m blaming your bright idea and driving off with the loot.” “Deal. Just don’t forget the goody bags. They always hide the best stuff in the goody bags.”
