Sergeant Jeffords: Hitchcock, Boyle needs you to fill out a line-up.
Hitchcock: Oh, great! I'll take my shirt off.
Charles: No one asked you to take your shirt off. Stop volunteering to take your shirt off.
Hitchcock: I can't hear you. Shirt's over my ears!

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.

Charles: Hey, Sarge. I need someone to fill out a line up. Will you be scary Terry?
Sergeant Jeffords: Oh, I love being Scary Terry. He says what regular Terry's thinking.

Sergeant Jeffords: This is taking too long! I'm gonna miss the farmer's market!

Jake: I have a murder here with no leads and no evidence. It's unsolvable, and thus, shall have no paperwork.

Jake: I don't slump, people. I opposite of slump. I pmuls. That's slump backwards and it's what I do. I pmuls all over this bitch.
