The Hitchhiker's Guide to the Galaxy, Radio Series

Marvin:
No, not one of those.

Frogstar Robot:
Good though isn't it?

Marvin:
Very good.

Frogstar Robot:
I know, you must have one of those new Xanthic Re-Structtion Destabilised Zenon Emitters.

Marvin:
Nice, aren't they?

Frogstar Robot:
That what you got?

Marvin:
No.

Frogstar Robot:
Oh, then it must be one of those things with twirls... goes whoosh...

Marvin:
You're thinking along the wrong lines you know, you're failing to take into account something very basic in the relationship between men and robots.

Frogstar Robot:
I- I- I- I know it I know it, I've seen them. Quite big... er...

Marvin:
Look, look, no, just think. They left me - an ordinary, menial robot - to stop you - a gigantic, heavy-duty battle machine - whilst they ran off to save themselves… What do you think they would leave me with?

Frogstar Robot:
Well, er, something pretty damn devastating I would expect.

Marvin:
Expect? Oh yes, expect. I'll tell you what they gave me to protect myself with, shall I?

Frogstar Robot:
Yes all right.

Marvin:
Nothing.

Frogstar Robot:
What?

Marvin:
Nothing at all. Not an electronic sausage.

Frogstar Robot:
Well, doesn't that just take the biscuit!

Marvin:
And me with this terrible pain in all the diodes down my left side.

Frogstar Robot:
Yeah? Oh that makes me angry, think I'll smash that wall down.
