Rosa: Clearly you don't know me at all.
Charles: What? We're friends. I was building up to calling you Ro-ro one of these days.

Marcus: It was all Charles's idea.
Charles: I told you I knew you, Ro-ro.
Rosa: Thank you. But never call me Ro-ro again.
Charles: Oh, but I will. I've earned this.
Happy B-day, Ro-ro.

Captain Holt: I am sorry for getting so emotional.
Jake: Pretty consistent tone, actually.
Captain Holt: These have been the - These have been the best years of my career.
Jake: Oh no, this is new.
Captain Holt: And I know that everyone of you gave me everything you had. And I will never forget it.
Jake: Go back to being Robo-Captain.
Captain Holt: Meep-morp. Zeep. Dismissed.

Amy: Did I do something to you? Are you mad? Is this because I brushed all the crumbs off your desk?

Captain Holt: You have until tomorrow, you grackle.

Jake: In the immortal words of Amy Santiago, girlfriend please!

Jake: Who do you think it's gonna be?
Sergeant Jeffords: I've no idea.
Hitchcock: I bet it's me. I just hope I'm ready.

Jake: Okay, the reason I didn't want to work with you is - Should I do this in an accent to undercut some of the awkwardness I'm feeling?

Gina: Sir! I'm coming with you.
Captain Holt: Thank you, Gina.
Scully: I'm also coming.
Captain Holt: Not necessary.

Captain Holt: Don't count your gross fish babies before they've hatched, Madeline.

Rosa: That will never happen. In fact, you've just lost Rosa privileges. From now on, you can call me Diaz or Hey You.

Amy: We first met five years ago, but we don't count it because-
Jake: I was dating a speedboat model at the time.
Amy: And I was dating a super-handsome comptroller of a major U.S. city.

Jake: Man, I forgot how long your signature takes. I'm just gonna watch Braveheart on my phone, real quick.

Jake: You know when you told me you didn't want to date cops?
(In Jamaican accent) That really bummed me out, man.

Rosa: Jake, you need a jacket or something.
Charles: Well, Scully left his sports coat back there. Oh, but it'll never fit Jake's athletic body.
Unless.
Jake: No, I don't want to do that.
Charles: You have to.
Jake: I'm not going to do it.
Charles: You're doing it.
Amy: What do you have to do?
Jake: Don Johnson it.
