Spock: What's that you're writing, Ensign?
Chekov: Words of Wisdom. See what I do is, copy down cool shit that you and the Captain and Dr. McCoy say. I plan on writing a book when this mission is over.
Spock: Well, let's see what you have so far.
Chekov: All right, look at this... (reading) "Sometimes you've got to crack a few eggs to make an omelet."
Spock: You've got to crack a few eggs to make an omelet?
Chekov: Yeah, you gotta crack an egg.
Spock: When did anyone say that?
Chekov: I think you said it. Or someone did. Anyway, it's good advice. Sort of a life lesson.
Spock: So you're throwing down life lessons now?
Chekov: I'm throwing down eggs!
Spock: Class is in session, Chekov's teaching class now!
Chekov: I'm cracking eggs of wisdom!
