DOCTOR: Never be cruel. Never be cowardly. Hate is always foolish. Love is always wise. Always try to be nice, but never fail to be kind.

DOCTOR: People plus technology minus humanity. The internet, cyberspace, Cybermen. Always read the comments, because one day they'll be an army.

DOCTOR: They're not your rescuers. They're your replacements. The end point of capitalism. A bottom line where human life has no value at all. We're fighting an algorithm, a spreadsheet. Like every worker, everywhere, we're fighting the suits.

RAM: What about football?

DOCTOR: Unbelievably boring sport. Now, darts? Darts is something worth practising for. Maths and alcoholic beverages. The best way to spend a morning.

DOCTOR: Oh, come on! Cheer up! It's not that hard. It's no harder than all these exams that you have to take these days. Except for Media Studies. It's going to be harder than that.
