“Ford carried on counting quietly. This is about the most aggressive thing you can do to a computer, the equivalent of going up to a human being and saying "Blood...blood...blood...blood...”

“It is worth repeating at this point the theories that Ford had come up with, on his first encounter with human beings, to account for their peculiar habit of continually stating and restating the very very obvious, as in "It's a nice day," or "You're very tall," or "So this is it, we're going to die."

His first theory was that if human beings didn't keep exercising their lips, their mouths probably shriveled up.

After a few months of observation he had come up with a second theory, which was this--"If human beings don't keep exercising their lips, their brains start working.”
― Douglas Adams, The Restaurant at the End of the Universe

“One of the major difficulties Trillian experienced in her relationship with Zaphod was learning to distinguish between him pretending to be stupid just to get people off their guard, pretending to be stupid because he couldn't be bothered to think and wanted someone else to do it for him, pretending to be outrageously stupid to hide the fact that he actually didn’t understand what was going on, and really being genuinely stupid. He was renowned for being amazingly clever and quite clearly was so—but not all the time, which obviously worried him, hence, the act. He preferred people to be puzzled rather than contemptuous.”
― Douglas Adams, The Hitchhiker’s Guide to the Galaxy
