Eliza - computerized psychotherapist
I found this program back in the 1970's and I programmed it into an old TI99-4a (micro computer). It gave me hours and hours of fun. The program itself is very simple but sometimes you really wonder if the ghost of some psychiatrist has snuck into your PC.
Quote from Introduction to Artificial Intelligence

The name Eliza was chosen as "it" could learn to talk increasingly well as did Eliza of Pygmalion fame.
You asked Eliza questions and she (it?) responded.
