Lyrics:

[Rachel]: Do you like our owl?
[Deckard]:It's artificial?
[Rachel]: Of course it is.
[Deckard]: Must be expensive.
[Rachel]: Very.
[Rachel]: I'm Rachel.
[Deckard]: Deckard.
[Rachel]: It seems you feel our work is not a benefit to the public.
[Deckard]: Replicants are like any other machines. They are either a benefit or a hazard. If they're a benefit, it's not my problem.
[Rachel]: May I ask you a personal question?
[Deckard]: Sure.
[Rachel]: Have you ever retired a human, by mistake?
[Deckard]: No.
[Rachel]: But in your position that is a risk?
[Tyrell]: Is this to be an empathy test? Capillary dilation of the so called blush response... fluctuation of the pupil... involuntary dilation of the iris?
[Deckard]: We call it Voight-Kampf for short.
[Rachel]: Mr. Deckard, Dr. Elden Tyrell.
[Tyrell]: Demonstrate it. I want to see it work.
[Deckard]: Were is the subject?
[Tyrell]: I want to see it work on a person. I want to see a negative before I provide you with a positive.
[Deckard]: What's that gonna prove?
[Tyrell]: Indulge me.
[Deckard]: On you?
[Tyrell]: Try her.
