Beckett: Exactly how many times have you been married, Castle?
Beckett: That's it?
Castle: Isn't that enough? How 'bout you?
Beckett: Me? No. Never been.
Castle: You'd be good at it, you're both controlling and disapproving. You should really try it.
Beckett: I'm not an "if at first you don't succeed" kind of a girl, Castle, when it comes to marriage, I'm more of a "one and done" type.
Castle: Hmm, any serious candidates?
Lawyer: Mr. Castle, be advised, if you get injured following Detective Beckett to research your next novel, you cannot sue the city. If you get shot, you cannot sue the city. If you get killed...
Castle: My lifeless remains cannot sue the city?
Lawyer: Your heirs, Mr. Castle.
Beckett: Do I have to wait for him to sign, or can I shoot him now? [Then mouthing, "No? OK."]
Lawyer: Mr. Castle, these waivers are serious business, perhaps you'd feel more comfortable by referring the matter to your attorney?
Castle: What, are you kidding? He'd never let me sign these! But fortunately it's his job to get me out of trouble, and not to prevent me from getting into it.
