Just chat with Cleverbot. While the Bot may seem stupid at first, it will eventually pick up the kinds of things people may say and will get smarter, very similar to the real Cleverbot. Please share any funny conversations you have with Cleverbot! Here's one of mine. Me: Are you alive? Cleverbot: No. Me: Why aren't you alive? Cleverbot: I can't answer you there.
Cleverbot is not all my idea. The original Cleverbot is at cleverbot.com. Enjoy! Update v. 3.2: A bug with Cleverbot was fixed and his answers to questions will now make much more sense.
