Deckard: Remember when you were six? You and your brother snuck into an empty building through a basement window. You were going to play doctor. He showed you his, but when it got to be your turn you chickened and ran; you remember that? You ever tell anybody that? Your mother, Tyrell, anybody? Remember the spider that lived outside your window? Orange body, green legs. Watched her build a web all summer, then one day there's a big egg in it. The egg hatched...
Rachael: The egg hatched...
Deckard: Yeah...
Rachael: ...and a hundred baby spiders came out... and they ate her.
Deckard: Implants. Those aren't your memories, they're somebody else's. They're Tyrell's niece's.
Deckard: [he sees that she's deeply hurt by the implication] O.K., bad joke... I made a bad joke. You're not a replicant. Go home, O.K.? No, really - I'm sorry, go home.
