Charles: Let's take these hats out for a spin. I've waited long enough. Here you go. Best Bud #1.
Jake: You'd rather be Best Bud #2?

Jake: Okay, good, 'cause I really wanted to be Best Bud #1.

Charles: Ooh, they're tight.
Jake: They're way too small.

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.

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.
