So, I know this is a rather old page but I just discovered it and I got to say I haven't laught so hard because of a pc yet haha
Cleverbot, from Wikipedia:
Cleverbot is an AI web application that learns how to mimic human conversations by communicating with humans. It was created by AI scientist Rollo Carpenter, who also created Jabberwacky, a similar web application. In the first decade of its existence after being created in 1988, Cleverbot held several thousand conversations with Carpenter and his associates. Since being launched on the web in 1997, the number of conversations has exceeded 65 million.
So just post funny conversations you had with Cleverbot!:)
