- Tegan Jovanka: You call three hundred years a small error?
- The Fifth Doctor: It's probably due to nothing more than a temperamental cellanoid on the lateral balance cones.
- Tegan Jovanka: Is that supposed to be Heathrow?
- Adric: It is.
- Tegan Jovanka: Well, they've certainly let the grass grow since I was last there.
- Adric: Well, actually they haven't built the airport yet. We're about three hundred years early.
- Tegan Jovanka: That's great. Perhaps I can go out, file a claim on the land. When they get 'round to inventing aircraft I'll make a fortune!
- The Fifth Doctor: Try to understand, Adric: because you get away with something, it doesn't justify it.
- Richard Mace: [explaining his possession of guns] I was once a noted thespian until forced into rural exile by the closure of the theaters. But it is only with the aid of these properties I'm able to command the attention of an audience nowadays.
- Tegan Jovanka: You sound like a highwayman or a robber.
- Richard Mace: A gentleman of the road, madam.
- The Fifth Doctor: Oh.
- Nyssa: What?
- The Fifth Doctor: Look.
- Nyssa: Scarring from a high energy beam.
- The Fifth Doctor: And fired form a weapon.
- Nyssa: So much for my friendly aliens.
- Tegan Jovanka: You call yourself a Time Lord? A broken clock keeps better time than you do! At least it's accurate twice a day... which is more than you ever are!
