Gina: What are you saying, Terry? You think I can't handle being back yet? (CHUCKLES) Watch this. (Gina dances to Salt 'n Peppa's "Push It" in a stilted, robotic manner while screaming in agony)
Hitchcock: Gina Linetti is back, baby!

Amy: Hey, I think I found something interesting. I was double-checking last month's surveillance photos, and I noticed this. Hawkins has two different phones: her normal cell, and then this one that only has one app on the home screen Snapchat.
Hitchcock: Oh, she's up to something. Snapchat messages disappear. You can send anything to anybody, and after they see it, it's like I never sent it.
Captain Holt: Nobody ask Hitchcock why he knows that.

Sergeant Jeffords: Hitchcock called himself Scully by accident.
Hitchcock: I did, but it brought me and Scully closer together.

Amy: Hitchcock, why do you have your shirt off?
Hitchcock: Can't spill food on your shirt if you're not wearing one.

Captain Holt: Sergeant, please tell me this malfunctioning copier isn't gonna sink our precinct.
Sergeant Jeffords: I figured out how to turn it on, but the screen just shows a cartoon turtle sobbing.
Captain Holt: Perhaps it's a paper jam.
Sergeant Jeffords: And what about when the little sushi roll comes out and cuts the turtle's head off?
Captain Holt: Toner issue.
Sergeant Jeffords: Why?!

Sergeant Jeffords: There's something I'd like to show you, Captain.
(Japanese copier starts up)
Captain Holt: "Terry crushed it." It works! I've never been more proud of you for anything in your life.
Sergeant Jeffords: I mean, I've solved a lot of cases for you.
Captain Holt: And yet crime has continued.

Jake: Why'd you have to say he was boring?
Amy: Because he is boring. His favorite app on his phone is "contacts."
