Captain Holt: Santiago, you're putting yourself under too much pressure. And that stress is making it even harder for you to quit. Some things might come easier to you if you stop being such a perfectionist. A concept you should become familiar with.
Amy: "Familiar with?" Mmm, a dangling preposition?
Captain Holt: I'm setting an example. I made an error and I'm not going to correct it. I'm just gonna let it dangle Dangle Dangle.
Amy: Thank you, Captain.

Rosa: All you have to do is say a few nice comments during the memorial.
Captain Holt: As God said when Wuntch tried to sneak past the gates into heaven, "It ain't happening, honey."
Rosa: [cackles]

Amy: Maybe we should talk about deets for the case. Plan our next move. Grab some chow.
Captain Holt: No need. I brought these. Nutrition bricks. I have original no flavor, and whole wheat no flavor.

Jake: We have a few more questions for you, doctor.
Captain Holt: Doctor. Huh. It's funny when people call dentists "doctor".
Philip Davidson: We are doctors. We do four years of medical school.
Captain Holt: Yeah, but it's called "dental school".
Philip Davidson: But we learn about the entire body.
Captain Holt: But if you had cancer, you wouldn't call a dentist.
Philip Davidson: You know it's actually harder to get into dental school than medical school.
Captain Holt: Well, because there are fewer dental schools. Because most people want to become actual doctors.
Philip Davidson: That's ridiculous. It's not like we're college professors calling ourselves "doctors".
Captain Holt: Not the same thing, my friend.
Philip Davidson: Well, sure it is. When someone has a heart attack on a plane, do they yell out, "Yo, does anybody here have an Art History PhD?"
Captain Holt: A PhD is a doctorate. It's literally describing a doctor.
Jake: Maybe let's refocus.
Captain Holt: No! The problem here is that medical practitioners have co-opted the word "doctor".
Jake: Okay, Captain-
Captain Holt: I know we live in a world where anything can mean anything, and nobody even cares about etymolo-
[cut to outside, Holt downing a glass of water]
Captain Holt: Apparently that's a trigger for me.
Jake: Yeah, apparently.

Jake: Boyle, why don't you show Danger what a fax machine is.
Charles: Okay. Imagine a letter had unprotected sex with a phone.

Jake: Here, my email is-
Jack Danger: Uh, no email. I'll send it to you with r-mail, which is to say, real mail. Because email has put hundreds of my co-workers out of work.
How would you like it if they laid off all of your fellow detectives and partnered you with a robocop?
Jake: I've literally drawn sketches of that.
Charles: The robot has a backpack that can carry me.

Captain Holt: Santiago, I may need you to come in for a bit on saturday.
Amy: Again? Are you kidding me, man? (Gasps) I'm sorry. Let's start fresh. Hi!
Sergeant Jeffords: Oh, my God.
Captain Holt: What just happened?
Gina: Her mind finally snapped, like a stale breadstick.
