I typed this one, word for word while reading the subtitles on my dvd.

The Doctor: You are so Scottish. How am I doing?
Voice Interface: Your system has been contaminated by the poison of the Judas Tree. You will be dead in 32 minutes.
The Doctor: Okay, so, basically better regenerate. That's what you're saying?
Voice Interface: Regeneration disabled. You will be dead in 32 minutes.
The Doctor: Unless I'm cured, yeah?
Voice Interface: There is no cure. You will be dead in 32 minutes.
The Doctor: Why do you keep saying that?
Voice Interface: Because you will be dead in 32 minutes.
The Doctor: You see? There you go again. Basically skipping 31 whole minutes when I'm absolutely fine. It's Scottish, that's all I'm saying.
Voice Interface: You will be fine for 31 minutes. You will be dead in 32 minutes.
The Doctor: Scotland's never conquered anywhere, you know. Not even a Shetland. River needs me. She's only just beginning, I can't die now.
Voice Interface: You will not die now. You will die in 32 minutes.
The Doctor: I'm going out in the first round. Ringing any bells?
