Beckett: Murdered Medina just to boost ticket sales? No, that would make this Scooby-Doo... And I'm not Velma.
Castle: Velma, you kidding? You're Daphne... You're hot, smart, not aggressively brainy, but long legs, short skirt...
Castle: Got it.
Castle: I can't believe you got dressed up for this. Tell me again why Ryan and Esposito couldn't come with you?
Beckett: Well, they agreed as a volunteer assistant homicide detective you could really sink your teeth into this avenue of investigation. And they called "not it."
Castle: You know, ever since I've been following you, I've been dreaming of the day that you'd say "let's go to the strip club and get this dirt bag." I just never imagined it would feel like this.
Beckett: Let me know if you need any singles.
Capt Montgomery: Feds say he's a white male, 25 to 45 years old...
Castle: Could be me.
Capt Montgomery: With a dysfunctional relationship with his mother...
Castle: Still me.
Capt Montgomery: He has a menial, unimportant job...
Beckett: Definitely you.
Castle: Just for that, I base my next book on Esposito.
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?
Ryan: You know what I don't get?
Ryan: Why go to so much trouble to create such an elaborate scam? Fletcher must have spent weeks going through all the prep work.
Beckett: I can give you 50,000 reasons why.
Castle: Yeah, but for con men, it's not just about the money. I mean, for them, it's about the game. The... The thrill they get from pulling a con, it's like a drug high.
Montgomery: [approaching] Con man was on drugs?
Beckett: No, sir. Castle is just giving us psychological insight based on his extensive experience as a fraud.
Castle: Alright, so you and I are married.
Beckett: We are not married!
Castle: Relax, it's just pretend.
Beckett: I don't want to pretend!
Castle: Scared you'll like it?
Beckett: OK, if we're married, I want a divorce!
Roger: Are you two like this all the time?
Castle and Beckett: [Together] Yes!
Beckett: Castle, if we were getting married, would you want to know about all the guys that I've slept with?
Castle: All... ?
Beckett: Seriously? You sign women's chests at book readings, you cannot be shocked that I'm not a virgin.
Castle: Ahh, it's just the word, "all" suggests... A lot. How many we talkin', exactly?
Beckett: Are you really asking for my number?
Castle: You show me yours, I'll show you mine.
Beckett: [With a sly smile on her face.] Men. You all wanna know, but you don't wanna know.
Beckett: Did you seriously stay up staring at this Scrabble board all night instead of going to bed?
Castle: With these five remaining tiles, I have to craft a word scoring 9 points... And I turn defeat, into victory.
Alexis: Oh, my gosh, did you really beat dad at Scrabble?
Castle: I concede nothing! Except that I need more coffee.
Martha: That is quite an accomplishment young lady... Nobody beats him, ever!
Beckett: Oh yeah, he's mentioned that... Repeatedly.
Martha: Ahhh, how the mighty have fallen!
Castle: Richard Castle, one word short... I cannot allow this to be my epitaph.
[Beckett and Alexis slyly fist-bump each other.]
Castle: I saw that!
