Scully: Why do I think that Charles Darwin is rolling in his grave right now.

Mulder: What did your examination uncover?
Scully: Well, I... I haven't exactly performed an examination yet.
Mulder: Why not?
Scully: Well. Because I, uh … I experienced an unusual degree of postmortem galvanic response.
Mulder: The head moved.
Scully: It blinked at me. I mean, I... I know exactly what it is. It's residual electrical activity stored chemically in... in the dead cells.
Mulder: Blinked or winked?
