I remember writing a little script to make megahal chat in a P2P network chat room about 2 decades ago...
It was really funny see all the users chatting with it. We admins kew what it was, but other users really had the most interesting conversations with it.
Some people got angry with it, suspecting a troll.
Downside was that after a few weeks the bayesian database got so big that I had to restart it periodically to avoid stalling my work station.
