Season 1, Episode 6
(about Meridith)
Castle: She's thinking of moving back to New York. Do you know what that would mean to me? That would be a very special brand of hell. The hell of a deep-fried twinkie.
Ryan: A deep-fried twinkie?
Castle: Yeah, the guilty pleasure that you know is bad for you so you only do it once, maybe twice a year for the novelty
Beckett: Castle!
Castle: What?
Beckett: Crime scene, dead body. A little respect here.
Castle: I don't think he can hear me.
Beckett: If she's so bad, why did you have sex with her this morning?
Castle: Let me tell you something about crazy people. The sex is unbelievable.
Beckett: How shallow are you?
Castle: [soberly] Very.
