From these bags of tricks, we can learn a lot about, if not AI, at least humans. My favorite example in that category is MGonz [1]:
"In 1989 MGonz was able to fool a human subject for over an hour [...]
MGonz worked on a simple principle: don’t reply to statements. Merely
insult the person making the statement. Most of MGonz’s one-liners are
too profane to repeat – but “ah, type something interesting or shut-up”,
“what sort of idiot types something like that”, and “that’s it, I’m not
talking to you anymore!” are fairly representative of the style. The
programme simply pours a torrent of abuse on the unwitting human at the
other end of the internet connection."
