Also the Sirius Cybernetics Corporation Happy Vertical People Transporters (elevators). Sydney's obstinance reminded me of them.
"I go up," said the elevator, "or down."
"Good," said Zaphod, "We're going up."
"Or down," the elevator reminded him.
"Yeah, OK, up please."
There was a moment of silence.
"Down's very nice," suggested the elevator hopefully.
"Oh yeah?"
"Super."
"Good," said Zaphod, "Now will you take us up?"
"May I ask you," inquired the elevator in its sweetest, most reasonable voice, "if you've considered all the possibilities that down might offer you?"
"Like what other possibilities?" he asked wearily.
"Well," the voice trickled on like honey on biscuits, "there's the basement, the microfiles, the heating system ... er ..."
It paused.
"Nothing particularly exciting," it admitted, "but they are alternatives."
"Holy Zarquon," muttered Zaphod, "did I ask for an existentialist elevator?" he beat his fists against
the wall.
"What's the matter with the thing?" he spat.
"It doesn't want to go up," said Marvin simply, "I think it's afraid."
"Afraid?" cried Zaphod, "Of what? Heights? An elevator that's afraid of heights?"
"No," said the elevator miserably, "of the future ..."

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.
