Jake: Brace yourselves 'cause Jake-y is back. [mimics a train whistle] Don't everybody mob me at once. We can high-five one at a time. Oh, I see no response. A little "welcome back to the precinct" hazing. Who's behind this cute little prank? Diaz?
Rosa: Kill yourself.
Jake: Okay.
Amy: I told you. Night shift has everyone a little down.

Rosa: I want to say a few words. When Jason died seven days ago, I didn't give a rat's ass.
Charles: This is your speech?
Rosa: 'Cause I didn't understand why people care so much about their dumb dogs till I got a dumb dog myself. I've only had Arlo for a day and a half, but if anything happened to him, I would kill everyone in this room and then myself.
Gina: Very violent eulogy, I like it.

Rosa: Hey, you should run. Going to meetings, writing stuff down. You love that nerd stuff.
Amy: Writing stuff down is nerdy? What do you do?
Rosa: I just forget stuff like a cool person.

Sergeant Jeffords: Wait, is that a smile I see?
Rosa: Possibly. My immune system is too weak to fight off my smile muscles.

Sergeant Jeffords: Should I just go tell everyone to buck up and do their jobs?
Captain Holt: No, the squad's only on night shift because they came down to Florida to save Jake and me. It's my responsibility to fix this, so I'm going to brighten the mood by telling a few jokes. Try this one on for size: I don't care for cheese.I'm a curd-mudgeon. [silence] Wow. You're too tired for humor.

Charles: Now we just gotta pull his files from records.
Jake: Yep, then we bust him, and we'll be done with plenty of time before Nikolaj wakes up.
Charles: [correcting] Nikolaj.
Jake: Hm? Nikolaj, yeah, I said it.
Charles: Nikolaj.
Jake: Nikolaj.
Charles: Not even close. Nikolaj.
Jake: Nikolaj.
Charles: Almost. Nikolaj.
Jake: Nikolaj. I feel like I'm saying it.

Jake: Thank you, okay, so I break the back window, make my way over to the jewelry case. Meanwhile, you're standing lookout by the front door-
Charles: [French accent] Oui, oui.
Jake: Smoking a cigarette. Check it: Ash.
Charles: [French accent] Ooh la la. Okay, so I am smoking.
Jake: What are you doing?
Charles: Oh, Jacques rolls his own cigarettes, a habit he picked up from a prostitute in Marseille, but that is not all he picked up.
Jake: Why do all your characters get STDs?
Charles: [normal voice] Because they're living life!
