Dr. Parish: Looks like a patient lost his patience. Castle: Also his command of grammar. You're should be you-'-re as in you are, that's not even a tough one not like when to use who or whom. Beckett: Do you really think that's the take away here Castle? Castle: I'm just saying whoever killed her also murdered the English language.
Castle: What is it about full moons that bring out all the crazies? Beckett: I don't know, you tell me.
Ryan: How you doing, Dr. Perlmutter? Dr. Perlmutter: Shhhh! The body is speaking. Esposito: What's it saying? Dr. Perlmutter: It's saying "somebody shot me."
Esposito: Loser wears a dress to the precinct for a week. Ryan: And why stop there? Loser also shaves his head. Or are you chicken? Castle: You're on, honey milk.
Castle: You know, if this was one of those super-sciencey forensics shows, they'd stick some electrodes in these fishes' brains. Get a fish eye's view of whatever they saw.
Esposito: A warm milk nightcap with your lady? That is sad, bro. Ryan: It helps her sleep. Esposito: How about the sound of your voice? It works on me.
