Commander Goddard: Radu, raise the shields.
Radu: How do I do that?
Commander Goddard: I don't know.

When the crew are trying to stop their doppelgangers, Miss Davenport encounters hers.
Evil Davenport: So now I guess you're going to give me demerits or faint or something?
Good Davenport: (very, very British) No, I believe I'll just punch your lights out. (Jumps into a Fighting Irish◊ fisticuffs pose.) Come and get it!
The best part? Good Davenport WINS.
So many of Miss Davenport's lines were this; unfortunately, her delivery and accent are what made them hysterical, which doesn't translate to text very well. See in "Both Sides Now," when Android!Suzee is walking toward her with the probe to return her knowledge to the Christa.
Davenport: (very, very British) Now where are you planning to stick that? (It was in her ear.)
