Back in the primordial days of AI, PARRY was an ELIZA-style chatbot created by psychiatrist Kenneth Colby to simulate the words of a paranoid schizophrenic. Someone had the genius idea to connect it to ELIZA (a.k.a. “DOCTOR”). Vint Cerf published the transcript as an RFC in 1973, and I laughed my ass off reading it. A taste:

Do you know anything about bookies?What makes you think I know anything about bookies?

A bookie didn’t pay me off once.What does that suggest to you?

I beat up the bookie who did not pay off, and I thought he might use his friends in the underworld to get even with me.What else would you like to discuss?

What do you know about racketeers?
