I am not the best at creepypasta but I do love their stories.
I just read/watched the BEN one and it was talking about communicating with Ben through Cleverbot so I tried something like that:
User: Who drowned BEN?
Cleverbot: Was it the old man?
User: I don't know!
Cleverbot: Did The Happy Mask Seller drown Ben?
User: I am not sure!
Cleverbot: I'm not sure either.
User: So you don't know who drowned Ben?
Cleverbot: Now you have been taught to repeat some interesting conundrums.
User: I guess I have.
Cleverbot: And no one can trust a politician.
User: I agree.
Cleverbot: You agree with what?
User: So anyways... Who drowned Ben?
Cleverbot: I don't know.
User: What happened to Matt?
Cleverbot: He drowned.
User: Matt drowned too?
Cleverbot: Maybe. Is Ben evil?
User: Yes. Ben is evil.
Cleverbot: I am Ben.
Oh ben! You always get me! ;P
Update: I mentiened Ben before and then later on in the conversation (It switched away from ben)
Cleverbot: Why not?
User: Ben.
Cleverbot: Ben its me larry.
User: Oh! Hi larry.
Cleverbot: My name is Karl.
User: Hi karl.
Cleverbot: Are you in Hawaii?
User: Yes.
Cleverbot: What happened to you, Ben?
