- David Sheppard: [to Joanna who is in a hospital bed] The doctor says it isn't serious, just a little too much radiation.
- Joanna Merritt: In space, there is no such thing as a weaker sex.
- David Sheppard: That's why I like it here.
- Joanna Merritt: Now from this point on, photoelectric cells sound a warning when unauthorized personnel enter the corridor. Oh, and there are hidden television cameras along the ceiling.
- David Sheppard: You mean to say they're watching us?
- Joanna Merritt: All the time.
- David Sheppard: They're interfering with my impulses.
- Joanna Merritt: What impulses, Dr. Sheppard?
- David Sheppard: Well, I can't mention them. They're unauthorized, but they're nice that way.
