“Bill, you’re joking. A kiddie party? With clowns and juice boxes?” “Exactly, Molly. No one suspects the piñata pinchers. We slip in during musical chairs, nab the gift table, and bolt before the cake’s cut.” “You want us to dress as what, disgruntled parents? I’m not wearing khakis.” “Better. I’ll be the hired magician. You’re my lovely assistant. We do one trick, then ‘oops’ the presents vanish. Classic misdirection.” “Kids scream louder than alarms, Bill. One tantrum and we’re done.” “That’s why we bring the emergency lollipops. Bribe the loud ones, chloroform the parents with the smell of cotton candy.” “Jesus, you’ve thought about this.” “Maps, blind spots, escape route past the bouncy castle. We’ll look like we’re just chasing a lost balloon.” “I hate you. Fine. But if I have to sing ‘Happy Birthday’ I’m keeping the biggest teddy bear.” “Deal. We hit the party at two, out by two-fifteen with every wrapped box under the sun. Think of it as Santa but with felony flair.” “You’re buying the face paint. And the getaway ice cream truck.” “Already rented. Sprinkles on the getaway vehicle included.”
