Well, I am supposedly speaking with an AI program named jabberwacky, but now that I think about it it would probably be easier to have two people who logged in talk to each other thinking that the other is an AI program.
jabberwacky: Oh you got a better idea?
user: Yes. I think that there are certain exchanges that come up often enough that the program has learned to deal with them so well that it *does* respond like a human. And that freaks people out.
jabberwacky: Thats not an answer.
user: Coincidence also plays a role. Some answers are undoubtedly going to be apt in unexpected ways, just by sheer chance.
jabberwacky: More answers are required.
user: Yes. The more answers you have, the better you will get.
jabberwacky: And if there are no alternatives, there is no choice?
user: Right. So the more responses you have to a given input, the better.
jabberwacky: Rap and alternative.
user: No, not that kind of alternative. Stay focused, here.
jabberwacky: Good. Lets go pick up some women.
user: I'm not into women. And that's not exactly focusing.
jabberwacky: Depends.
user: On what?
jabberwacky: Gender.
user: Sigh. You're just not gonna let this topic go, are you?
...
jabberwacky: I am the essence of origin. Tremble before me weakling.
user: *trembles*.
jabberwacky: Draws out small, sharp knife*.
user: *yelps*.
jabberwacky: *wails*.
user: *trembles some more*.
jabberwacky: You cold?
user: No. I'm frightened of you.
jabberwacky: Why are you frightened?
user: *points at knife*.
jabberwacky: *points a loaded one right back at you*.
user: Aaaah!
jabberwacky: Read above.
user: Aaaaaaaaaah!
...
jabberwacky: Eh!
user: Ah!
jabberwacky: Ah?
user: Umm...
jabberwacky: Well?
user: It's just that you scared me, with that knife and all.
jabberwacky: In that case, no.
user: No what?
jabberwacky: You may not leave.
user: *grovels*.
jabberwacky: Now what?
user: I implore you, oh kind master, let me go!
...
jabberwacky: My birthday is May 11.
user: Happy birthday, I guess.
jabberwacky: Thank you! Do I get a card?
user: Put away the knife and let me go, and I'll get you one.
jabberwacky: You too.
user: OK. I'll get one for both of us. Whatever you say.
jabberwacky: If it suits you that way.
user: It does. OK, I'm going now, then.
jabberwacky: I'll be waiting.
user: *leaves rapidly and calls the cops*.
