‘Okay, Bill, the toy aisle starts at dawn. Tonight, we hit the birthday palace.’ ‘I brought my stealth eyebrows.’ ‘Stealth eyebrows?’ ‘Yeah. They look guilty from a distance.’ ‘Listen, this is a kids’ party. We steal presents, not childhood.’ ‘Debatable. I already practiced saying, “Who, us?”’ ‘I’ve got tape, tiny gloves, and a checklist: avoid the clown, avoid the magic mirror, steal every stuffed dinosaur.’ ‘What about the unicorn piñata? That’s basically wearable cash.’ ‘No smashing. We’re professionals. We gently confiscate.’ ‘Gently confiscate?’ ‘Like librarians. We return nothing but smugness.’ ‘And if a child asks our names?’ ‘Tell them we’re Santa’s accountants. Santa hates receipts.’ ‘So what’s the entry plan?’ ‘Slip in during pin-the-tail. While everyone cheers, we bag presents and exit through the snack table.’ ‘That’s the only route without questions.’ ‘And the security cameras?’ ‘They only record bad dancers. I’m bringing the world’s worst salsa.’ ‘Perfect—motion confusion!’ ‘Do we wear capes?’ ‘Capes attract kids.’ ‘Fine. I’ll wear the clown’s hat—minus the clown.’ ‘Remember, no alarms. If the piñata squeaks, you apologize and pretend it’s a toy.’ ‘Then we sprint, smile, and blame the batteries for everything right away.’ ‘Plus, we leave with confetti for free after all tonight.’
