Here you'll find short, quotable sound clips from the voices of Marvin. Feel free to save and use however you want, but DO NOT direct link.

Radio:
I'm feeling very depressed.
Don't talk to me about life.
Brain the size of a planet...
Pardon me for breathing.
I'm a personality prototype.
Do you want me to sit in a corner and rust?
No one can help me.
Pick a number, any number.
The Bridge Opening Speech
So much time, and pain as well...
Is there a last service you would like?

Movie:
I could calculate your chances of survival...
I'm feeling very depressed.
I want to get off.
Incredible, it's even worse than I thought.
That does absolutely nothing for me.
I've seen it. It's rubbish.
This will all end in tears.

Official Website:
If you must continue...
I'm so depressed.
Don't do that.
Brain the size of a planet...
Oh, for heaven's sake.
