"Bill, tell me you didn't bring a crowbar to a five-year-old's birthday party." "It's for the window, Molly, not for Timmy's face." "There's no window, Bill. There's a bouncy castle and forty screaming children. You're gonna crowbar a bouncy castle?" "I panicked, alright? You said 'break in' and my brain went full cat burglar." "It's a birthday party. The door's open. There's a sign that says 'Come In, Party's Started!'" "That feels like a trap." "It's optimism, Bill. Regular people have that." "So what's the plan, then? We just... walk in?" "We walk in, we say we're the balloon guy's assistants, we grab the presents, we walk out." "Balloon guy's assistants don't wear ski masks." "Fine, no masks. But I'm keeping the duffel bag." "The one that says 'LOOT' on it in glitter?" "I made it myself, Bill. Show some respect." "A six-year-old is gonna clock us in four seconds." "Six-year-olds believe in the tooth fairy. We'll be fine." "That's not reassuring." "Grab the cake too. I'm hungry." "We're stealing a cake now?" "Priorities, Bill. Priorities."
