Marvin de The Hitchhiker´s guide to the galaxy:

Marvin: ”I’ve been ordered to take you down to the bridge.
Here I am, brain the size of a planet and they ask me to take you down to
the bridge. Call that job satisfaction? ’Cos I don’t.”

Marvin: ”Pardon me for breathing, which I never do anyway so I don’t
know why I bother to say it, oh God I’m so depressed. Here’s another of
those self-satisfied door. Life! Don’t talk to me about life.”

Marvin: ”I think you ought to know I’m feeling very depressed,”
Trillian: ”Well here’s something to occupy you and keep your mind off things.”
Marvin: ”It won’t work, I have an exceptionally large mind.”
