Doctor Who: Shada

Romana:
I told you you've got the time wrong, Doctor.

The Doctor:
Yes, but you're always saying that.

Romana:
You're always getting the time wrong.

The Doctor:
Was it to do with the voices?

Professor Chronotis:
What voices?

The Doctor:
Well, when I was on the river, I heard a strange babble of inhuman voices. Didn't you, Romana?

Romana:
Yes.

Professor Chronotis:
Oh, undergraduates talking to each other, I expect. I've tried to have it banned.

Professor Chronotis:
I am, I was, I will be Professor Chronotis. Oh dear, we Gallifreyans have never managed to come up with a satisfactory form of grammar to cover these situations.
