Kate: "Babe, did you set your hair on fire again?"
Richard Castle: "That was one time. And no. No, no. I'm just, uh, so good-looking, I'm literally smoking hot."

Castle: "Alexis, I don't want to say 'You have some explaining to do', but I think you have some explaining to do."
Alexis: "Wait, did I forget to tell you I've been working P.I. cases for you?"
Castle: "Must have slipped your mind."
Alexis: "Hey, didn't the guys do a fantastic job remodeling the place?"
Castle: "I know, right? ... But you're changing the subject."

Castle: "How's the new boss lady treating you?"
Esposito: "She's ignoring me."
Ryan: "Just like every other woman in his life."

"Whoa! Looks like a Tarantino film came to life in here."

Assassin: "Keep walking. Head for the blue van."
Castle: "Oh, just the person I was looking for."
Assassin: "You know, most people react differently to a gun in their side."
Castle: "Yeah, well, this sort of thing happens to me a lot."

Hayley: "You really love her, don't you?"
Castle: "Like a house on fire."

Hayley: "Why is your wife visiting a disgraced former senator?"
Castle: "They have history."
Hayley : "What kind of history?"
Castle: "He had Beckett's mother killed."
