Jake: Okay, well, that was fun. Hey, why don't you go play over there, buddy? You can take this drug store receipt. It's very long and filled with coupons. You can fly it around like a kite.
Nikolaj: Whee!
Jake: Wow, kids are really basic. Is being a dad super easy?

Rosa: Come on, Peralta! Holt said to use the whole team. We all want this solved.
Jake: I appreciate the offer, but I work best alone. Except when it comes to sex. Actually, sometimes including sex.

Amy: I can't wait to see the inside of Raymond's house. I'm gonna learn everything there is to know about him.
Charles: I bet it's really fancy. Like Beauty and the Beast fancy.
Jake: No, it's probably just an empty, white cube with a USB port in it for him to plug his finger in when he's on sleep mode.

Jake: I wasn't hurt that badly. The doctor said all my bleeding was internal. That's where the blood's supposed to be.

Gintars: It's gift for Nikolaj.
Charles: Nikolaj?
Jake: How do you know Charles's son?
Gintars: My name is Gintars. From Latvia. I am Nikolaj birth father.
Charles: Ohh! Nikolaj's birth father who I'd never hope to meet. Very cool. Cool, cool, cool, cool, cool, cool, cool, cool, cool, cool, cool, cool, cool, cool, cool, cool, c-c-c-c-c [passes out]

Dr. Ronald Yee: The flies don't sense blood. They're just regular flies.
Amy: But, Dr. Yee, you can't be a fraud. You gave a TED Talk.

Amy: What are you saying out of your weird face?
Rosa: We put the flies near fresh blood, and nothing happened. They didn't react at all.
Captain Holt: Do you know how stupid these accusations sound? Diaz, you're fired.
Rosa: What?
Amy: Dr. Yee is one of the most respected forensic experts in the country.
Captain Holt: For you two - let's not mince words - common fools to suggest that you found the flaw in this brilliant man's-
Dr. Ronald Yee: They're right.
