Quote from Brick in Operation Infiltration
Dr. Fulton: So, what can I help you with? Brick: Well, I'm hatching a plan to infiltrate a friend group. Dr. Fulton: Uh-huh. [Brick places action figures on the desk] Uh... Is this the friend group you're talking about? Brick: No. Dr. Fulton: Ah! Brick: I've singled out a few kids in my robotics club... Dante and Parker. Their friend Max is moving to New York because his parents think he can do commercials. I personally don't see it, but I wish him luck. Anyway, this is my chance to get in with the other two. They're gonna need a new third. Dr. Fulton: Oh, I don't know. When it comes to friendship, three isn't always a good number. Brick: [chuckles] Have you not heard of the third wheel? It's classic. Like in a tricycle... The third wheel is what provides stability.
