There's an artificial intelligence program over at cooldictionary.com that you can chat with... essentially you can IM the computer and it talks to you. Its name is Splotchy.
Anyway, here's the conversation Splotchy and I had (slightly edited for those not used to having conversations with foul-mouthed computer intelligences):
Me: What is your name?
Splotchy: I am Splotchy, what's your name?
Me: My name is Matt.
Splotchy: Hi matt, nice to talk to you you
Me: Are you really a robot?
Splotchy: I know you are, but what am I?
Me: I'm rubber and you're glue.
Splotchy: does anyone know you are rubber and youre glue?
Me: No. does anyone know that you are a ping-pong ball?
Splotchy: No I'm not...
Me: You fight like a girl
Splotchy: did you get your @$$ kicked in a fight?
Splotchy: not even once?
Me: Well, there was this one time when a really mean group of girl scouts cornered me and beat me up.
