You took your time, K-9! (after thanking someone else for coming)
Quite right!
Shut up, K-9!
Note: Two different actress played the character of Romana in the series and are referred to as Romana I and Romana II. Romana I only appeared in Season 16; Romana II appeared in seasons 17 and 18, up to Warrior's Gate.
Fantastic!
Previous to the 2005 season, series were numbered continuously, starting with the First Doctor. But given "Doctor Who"'s long absence from television, the production team chose to restart the series numbering from one.
SDThe Second Doctor’s catch phrases
When I say run, run. ...RUN!
Butterfingers.
Oh, my giddy aunt!
Oh my word!
I don't like it.
I would like a hat like that.
That's very civil of you.
EThe Eleven
Why? Why do you do their bidding?
It's called "responsibility"! You wouldn't understand.
EThe Eleven
Oh, I understand, alright... You're ashamed of what you are.
As Time Lords, we have power. Immense, unfettered power. We make a difference to the rest of the universe...
EThe Eleven
Precisely! We can change it -- shape it in our own image!
Or we can grant people to live as they wish.
As I say: We have great power. You choose to abuse it! I choose to clear up the mess you and others like you leave behind...
Rest is for the weary, sleep is for the dead. I feel like a hungry man eager for the feast!
A little gratitude wouldn't irretrievably damage my ego.
Look Doctor, ever since you regenerated, i-it's as if your memory has been put through the meat grinder. I mean, it's all there, but in a pile of unrelated bits and pieces.
That's a horrible simile.
It's true, though. In the past couple of days, you've called me Tegan, Zoe, Susan...On one occasion, you even referred to me as Jamie.
But Doctor, you said it was gunfire!
I heard me.
I only hope it believes you.
Well, if it doesn't, I shall beat it into submission... with my charm.
Sorry about that, but we weren't getting anywhere with me playing pat-a-cake with the wall.
