TYRELL: Now now, Detective, it took you a lot longer than that, didn't it?

DECKARD: Well, you're very astute, Mr. Tyrell, and that's one of the things I wanted to ask you about. See, replicants don't normally have much in the way of memories because they're less than four years old. So how come [flips pages] Rachael remembers being a child?

[closeup on tyrell's face]

DECKARD: [poking at notepad] So uh, I did the Voight-Kampff test on your lady colleague here, like you asked, and I had some questions if that's alright with you.

TYRELL: Of course, Lieutenant. Do you mind if I ask, how many questions does it normally take?

DECKARD: Oh, well, see, that depends, and I'm not very good with these fancy machines, but we got a guy down at the precinct who can do it in fifteen, twenty questions, cross-referenced.
