quote:
From The Hitchhikers Guide To The Galaxy:
"Listen," said  Ford,  who  was  still  engrossed  in  the  sales
brochure, "they make a big thing of the ship's cybernetics. A new
generation  of  Sirius   Cybernetics   Corporation   robots   and
computers, with the new GPP feature.""GPP feature?" said Arthur. "What's that?"
"Oh, it says Genuine People Personalities."
"Oh," said Arthur, "sounds ghastly."
A voice behind them said, "It is." The voice was low and hopeless
and  accompanied  by a slight clanking sound. They span round and
saw an abject steel man standing hunched in the doorway.
"What?" they said.
"Ghastly," continued Marvin, "it all is. Absolutely ghastly. Just
don't  even  talk about it. Look at this door," he said, stepping
through it. The irony circuits cut into his voice modulator as he
mimicked  the style of the sales brochure. "All the doors in this
spaceship have a cheerful and  sunny  disposition.  It  is  their
pleasure  to  open for you, and their satisfaction to close again
with the knowledge of a job well done."
As the door closed behind them it became  apparent  that  it  did
indeed    have    a    satisfied   sigh-like   quality   to   it.
"Hummmmmmmyummmmmmm ah!" it said.
Marvin regarded it with cold loathing whilst his  logic  circuits
chattered with disgust and tinkered with the concept of directing
physical violence against it Further circuits cut in saying,  Why
bother?  What's  the point? Nothing is worth getting involved in.
Further circuits amused themselves  by  analysing  the  molecular
components  of the door, and of the humanoids' brain cells. For a
quick encore they measured the level of hydrogen emissions in the
surrounding  cubic  parsec  of  space and then shut down again in
boredom. A spasm of despair shook the robot's body as he turned.
"Come on," he droned, "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."
He turned and walked back to the hated door.
"Er, excuse me," said Ford following after him, "which government
owns this ship?"
Marvin ignored him.
"You watch this door," he muttered, "it's about to open again.  I
can   tell  by  the  intolerable  air  of  smugness  it  suddenly
generates."
With an ingratiating little whine the door slit  open  again  and
Marvin stomped through.
"Come on," he said.
The others followed quickly and the door  slit  back  into  place
with pleased little clicks and whirrs.
"Thank you the  marketing  division  of  the  Sirius  Cybernetics
Corporation,"  said Marvin and trudged desolately up the gleaming
curved corridor that stretched  out  before  them.  "Let's  build
robots  with  Genuine  People  Personalities," they said. So they
tried it out with me. I'm a personality prototype. You  can  tell
can't you?"
Ford and Arthur muttered embarrassed little disclaimers.
"I hate that door," continued Marvin. "I'm not getting  you  down
at all am I?"
"Which government ..." started Ford again.
"No government owns it," snapped the robot, "it's been stolen."
"Stolen?"
"Stolen?" mimicked Marvin.
"Who by?" asked Ford.
"Zaphod Beeblebrox."
Something extraordinary happened to Ford's face.  At  least  five
entirely separate and distinct expressions of shock and amazement
piled up on it in a jumbled mess. His left leg, which was in  mid
stride,  seemed to have difficulty in finding the floor again. He
stared at the robot and tried to entangle some dartoid muscles.
"Zaphod Beeblebrox ...?" he said weakly.
"Sorry, did I say something wrong?" said Marvin, dragging himself
on  regardless. "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."
