“Bill, you’re joking. A children’s party? We’re not stealing lollipops, we’re supposed to be professionals.” “Exactly, Mol. They’ll never suspect us. Think about it—twenty screaming kids, one stressed mum, and a mountain of brightly wrapped presents nobody’s guarding. It’s perfect.” “I swore after the clown museum job I’d never wear face paint again.” “You won’t need it. We go as the hired entertainers. I’m the magician, you’re the balloon artist. We do one trick, spike the punch with sleepy-time juice, and while the little monsters are napping we bag every gift under that giant rainbow banner.” “What if one of them wakes up and wants a pony balloon?” “Then you make him a pony balloon, Molly. A really complicated one that takes ten minutes. I’ll be in the gift corner filling my duffel like Santa on a bender.” “You realize we’re going to hell for this, right?” “Probably, but it’ll be a very festive hell. Look, we split the haul fifty-fifty. Half the kids get socks next year, we get PlayStations and whatever rich parents buy these days. Easy money.” “Fine. But if I get recognized by some tiny birthday tyrant I’m blaming you.” “Fair. Now help me pick a magic word that doesn’t sound dirty. ‘Abracadabra’ is taken.”
