Doctor Who (TV Series)
An Unearthly Child (1963)
Carole Ann Ford: Susan Foreman
The Doctor : This doesn't roll along on wheels, you know.
Barbara Wright : You mean, it moves?
Susan Foreman : The TARDIS can go anywhere.
Barbara Wright : TARDIS? I don't understand you, Susan.
Susan Foreman : Well, I made up the name TARDIS from the intials: Time And Relative Dimension In Space. I had thought you'd both understand when you saw the different dimensions inside from those outside.
Ian Chesterton : Let me get this straight. A thing that looks like a police box, standing in a junkyard, it can move anywhere in time and space?
Susan Foreman : Yes.
The Doctor : Quite so.
Ian Chesterton : But that's ridiculous!
Susan Foreman : Is that the book you promised me?
Barbara Wright : Yes.
Susan Foreman : [Barbara lends Susan the book on the French Revolution] Thank you very much. It will be interesting. I'll return it tomorrow.
Barbara Wright : Oh, that's not necessary. Keep it until you've finished it.
Susan Foreman : I'll have finished it.
Ian Chesterton : But that's ridiculous.
Susan Foreman : Why won't they believe us?
Barbara Wright : How can we?
The Doctor : Now, now, don't get exasperated, Susan. Remember the Red Indian. When he saw the first steam train, his savage mind thought it an illusion, too.
Ian Chesterton : You're treating us like children.
The Doctor : Am I? The children of my civilisation would be insulted.
