“The Encyclopedia Galactica defines a robot as a mechanical apparatus designed to do the work of a man. The marketing division of the Sirius Cybernetics Corporation defines a robot as "Your Plastic Pal Who's Fun to Be With. The Hitchhiker's Guide to the Galaxy defines the marketing devision of the Sirius Cybernetic Corporation as "a bunch of mindless jerks who'll be the first against the wall when the revolution comes,”

“Share and Enjoy' is the company motto of the hugely successful Sirius Cybernetics Corporation Complaints Division, which now covers the major land masses of three medium-sized planets and is the only part of the Corporation to have shown a consistent profit in recent years. The motto stands-- or rather stood-- in three mile high illuminated letters near the Complaints Department spaceport on Eadrax. Unfortunately its weight was such that shortly after it was erected, the ground beneath the letters caved in and they dropped for nearly half their length through the offices of many talented young Complaints executives-- now deceased.The protruding upper halves of the letters now appear, in the local language, to read "Go stick your head in a pig," and are no longer illuminated, except at times of special celebration.”

“Modern elevators are strange and complex entities. The ancient electric winch and “maximum-capacity-eight-persons" jobs bear as much relation to a Sirius Cybernetics Corporation Happy Vertical People Transporter as a packet of mixed nuts does to the entire west wing of the Sirian State Mental Hospital.This is because they operate on the curious principle of “defocused temporal perception.” In other words they have the capacity to see dimly into the immediate future, which enables the elevator to be on the right floor to pick you up even before you knew you wanted it, thus eliminating all the tedious chatting, relaxing and making friends that people were previously forced to do while waiting for elevators.Not unnaturally, many elevators imbued with intelligence and precognition became terribly frustrated with the mindless business of going up and down, up and down, experimented briefly with the notion of going sideways, as a sort of existential protest, demanded participation in the decision-making process and finally took to squatting in basements sulking.An impoverished hitchhiker visiting any planets in the Sirius star system these days can pick up easy money working as a counselor for neurotic elevators.”

“We already have the Wooden Pillar, the Steel Pillar and the Plastic Pillar. In a moment we will have the Golden Bail....'No, you won't.'We will,' stated the robot simply.No, you won't. It makes my ship work.'In a moment,' repeated the robot patiently, 'we will have the Golden Bail....'You will not,' said Zaphod.And then we must go,' said the robot, in all seriousness, 'to a party.'Oh,' said Zaphod, startled, 'can I come?'No,' said the robot, 'we are going to shoot you.'Oh, yeah?' said Zaphod, waggling his gun.Yes,' said the robot, and they shot him.Zaphod was so surprised that they had to shoot him again before he fell down.

“Trillian did a little research in the ship's copy of The Hitchhiker's Guide to the Galaxy. It had some advice to offer on drunkenness. "Go to it," it said, "and good luck.”

“We demand rigidly defined areas of doubt and uncertainty!”
