My observation is some of the best quotes are hard to trace to one person. Guess "Great minds think alike." Guess what? That's a quote of uncertain origin!
I think that would be more accurately called an aphorism. I like movie quotes. "I'm shocked... shocked to find that gambling is going on here!"
Here is an example of a quote from an unknown source that's amusing Artificial Intelligence is no match for natural stupidity.
"You can please some of the people some of the time all of the people some of the time some of the people all of the time, but you can never please all of the people all of the time." - Abraham Lincoln The opposite, however, is completely achievable. You can piss everyone off at once. - my own observation.
