- Dr. Who: [Steven does not accept a Viking helmet as proof that they have travelled through time] What do you think it is, a space helmet for a cow?
- Steven Taylor: You gave this ship a name just now, what was it?
- Vicki: TARDIS. T-A-R-D-I-S. It's stands for Time And Relative Dimensions In Space.
- Steven Taylor: IDBI.
- Vicki: What? IDBI?
- Steven Taylor: I-D-B-I.
- Vicki: Yeah.

- Dr. Who: Now, I suggest we take a walk along the beach and try and find a spot where the cliffs run down to sea level.

- Dr. Who: Yes, and possibly it might, but I'm not a mountain goat, and I prefer walking to any day. And I hate climbing.
