Tenth Doctor quotes from Doctor Who

Think you've seen it all? Think again. Outside those doors, we might see anything. We could find new worlds, terrifying monsters, impossible things. And if you come with me... nothing will ever be the same again!

[posing as a teacher, introducing himself to class] So, physics! Physics, eh? Physics! Phyyyysics! [catches himself] I hope you're getting all this down!

Human race. For such an intelligent lot, you aren't half susceptible. Give anyone a chance to take control, and you submit. Sometimes I think you like it. Easy life.

Oh, Lumic, you're a clever man. I'd call you a genius, except I'm in the room. But everything you've invented, you did to fight your sickness. And that's brilliant. That is so human. But once you get rid of sickness and mortality, then what's there to strive for, eh? The Cybermen won't advance, you'll just stop! You'll stay like this forever. A metal Earth with metal men and metal thoughts, lacking the one thing that makes this planet so alive: people! Ordinary, stupid, brilliant people!

[about Rose] I've seen fake gods and bad gods and demigods and would-be gods; out of all that, out of that whole pantheon, if I believe in one thing... just one thing... I believe in her.

Crossing into established events is strictly forbidden. Except for cheap tricks.

[determined to go after Martha] I'm finding my own way. I usually do. [opens hatch with sonic screwdriver] There we go [takes off coat and tosses it to Valerie] Look after this. [looks down hatch, then up again longingly] I love that coat. Janis Joplin gave me that coat.

Daleks are bad enough at any time, but right now they're vulnerable, and that makes them more dangerous than ever.

Really shouldn't take that long just to reverse the polarity. I must be a bit out of practice...

Fascinating race, the Weeping Angels. The only psychopaths in the universe to kill you nicely. No mess, no fuss, they just zap you into the past and let you live to death, the rest of your life used up and blown away in the blink of an eye. You die in the past and in the present they consume the energy of all the days you might have had. All your stolen moments. They're creatures of the abstract, they live off potential energy.

People assume that time is a strict progression of cause to effect, but actually, from a non-linear, non-subjective viewpoint, it's more like a big ball of wibbly-wobbly... timey-wimey... stuff.

And... that's it, I'm afraid. That's the last I got on the transcript. I don't know what's stopped you talking, but I can guess. The Angels are coming for you. But listen, your life could depend on this. Don't blink. Don't even blink. Blink and you're dead. They are fast, faster than you can believe. Don't turn your back, don't look away, and don't blink. Good luck.

[speaking on human evolution and the refugees] Oh, might have spent a million years evolving into clouds of gas... and another million as downloads, but you always revert to the same basic shape: the fundamental human. End of the universe and here you are. Indomitable, that's the word! Indomitable! Ha!

You wouldn't listen. Because you know what I'm going to say...

I forgive you.
