Lyrics:

[Rachel:]
'Do you like our owl?'

[Deckard:]
'Is it artificial?'

[Rachel:]
'Of course it is'

[Deckard:]
'Must be expensive'

[Rachel:]
'very'

[Rachel:]
'I'm Rachel'

[Deckard:]
'Deckard'

[Rachel:]
'Its 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?'

'Capilary dilation of the so called blush response'
'... fluctuation of the pupil'
'Involuntary dilation of the iris'

[Deckard:]
'We call it Voight-Kampf for short'
[note: named after the people who developed this test]

[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'
