Dr who fourth doctor quotes The Horns of Nimon

Romana II: Don't you think that's a bit dangerous?

The Doctor: No I don't. What could possibly go-

The Doctor: -wrong. You know, I've simply got to stop saying that! Every single time I say "What could possibly go wrong" something goes-

The Doctor: It's uncanny! Isn't it?

The Doctor: Have you noticed how people's intellectual curiosity begins to decline the moment they start waving guns about?

The Doctor: Why don't you give me the gun and then I can keep an eye on myself so I don't get up to any funny business.

The Doctor: Here, take this you might need it.

Romana II: No thank you. I've made my own.

The Doctor: Oh really? Really? You made this? Not bad, a bit basic though. Thank you! Now...

Romana II: Uh, Doctor?

The Doctor: Yes?

The Doctor:Oh, ha ha, so sorry.

The Doctor: Estimated time to impact?

K-9: Master?

The Doctor: How long have we got?

K-9: Estimated time to impact-

The Doctor: That's what I said!

K-9: 89.4 seconds.

The Doctor: 89.4 seconds? No dematerialisation, no defense shields and only half power on full drive. K-9, I think we're going to find out what it's like to be a cricket ball. Well, it's been a great, great partnership old girl.

K-9: Master.

The Doctor: Oh K-9, This is no time for emotional quibbling you two. You've been a good dog to me, K-9. The best I ever had!

K-9: Thank you Master. Time to impact now 58 seconds dead.

The Doctor: I wish you wouldn't say things like that, K-9.

The Doctor: You know K-9, sometimes I think I'm wasted just rushing about the universe saving planets from destruction. With a talent like mine I might have been a great slow bowler.

The Doctor: Did you know that someone is building a black hole on your doorstep?

Soldeed: What?

The Doctor: Yes. I got stuck in it along with one of your spacecraft.

Nimon: Later you will be questioned, tortured and killed.

The Doctor: Well I hope you get it in the right order.

Soldeed: You! You meddlesome hussy! Do not touch the sacrifices!

Romana II: It's all over, Soldeed, you're finished.

Soldeed: No! The Nimon will fulfill his great promise, the Nimon be praised!

Romana II: The Nimon be praised? How many Nimons have you seen today?

Soldeed: I have seen the Nimon.

Romana II: How many?

Soldeed: Skonnoth will-

Romana II: How many Nimons?

Soldeed: Threeeee! I have seen three!

Romana II: Well I've just seen a whole lot more rampaging down the corridor. Face it Soldeed, you're being invaded!

Soldeed: My dreams of conquest!! You have brought this calamity upon me!

Romana II: You've brought it on yourself!

Soldeed: You will die for your interference!

Romana II: Stop him!

Soldeed: You fool! You are all doomed!! Doomed!!

The Doctor: K-9, is there a wall in front of us?

K-9: Negative, Master.

The Doctor: Then off you go then.
