Quote context

[...]

- You talk about him as if he had occasional bad manners.

- No. I don't know. I'm just a hack writer who drinks too much and falls in love with girls... You.

- Me?

- Don't be such a fool. Of course.

- If you'd rung me up and asked me were you fair or dark or had a moustache, I wouldn't have known.

- Oh, I am leaving Vienna. I don't care whether Harry was murdered by Kurtz or Popescu or the third man.

- Whoever killed him, there was some sort of... justice. Maybe I would've killed him myself.

- A person doesn't change because you find out more.

- Look. I've got a splitting headache, and you stand there and just talk and talk and talk. I... I hate it.

- That's the first time I ever saw you laugh. Do it again.

- There isn't enough for two laughs.

- I'd make comic faces and stand on my head and grin at you between my legs, and tell all sorts of jokes...

- I wouldn't stand a chance, would I?
