The scene: London. Our heroes Ford Prefect and Arthur Dent are sitting in Arthur's house when, amidst the cacophony of machinery, there marches down the ramp of a space ship "an immense silver robot, a hundred feet tall."
It held up a hand.
"I come in peace," it said, adding after a long moment of further grinding, "take me to your Lizard."
Ford Prefect, of course, had an explanation for this...
"It comes from a very ancient democracy, you see...."
"You mean, it comes from a world of lizards?"
"No," said Ford..., "nothing so simple. Nothing anything like so straightforward. On its world, the people are people. The leaders are lizards. The people hate the lizards and the lizards rule the people."
"Odd," said Arthur, "I thought you said it was a democracy."
"I did," said Ford. "It is."
"So," said Arthur, hoping he wasn't sounding ridiculously obtuse, "why don't the people get rid of the lizards?"
"It honestly doesn't occur to them," said Ford. "They've all got the vote, so they all pretty much assume that the government they've voted in more or less approximates to the government they want."
"You mean they actually vote for the lizards?"
"Oh yes," said Ford with a shrug, "of course."
"But," said Arthur, going for the big one again, "why?"
"Because if they didn't vote for a lizard," said Ford, "the wrong lizard might get in."

You don't have to choose from among the lesser of two lizards. There really is an alternative.
