I'm probably way behind on the times, but I just found Cleverbot and had this conversation:
Me: How many more papers should I grade.
Cleverbot: What are you talking about?
Me: The papers. How many?
Cleverbot : All these personality switches and misunderstandings.
Me: Seriously, too many.
Cleverbot: Yes, you are right, my liege! I see it now! Icon was behind the silo razings, and if we hire a hero to bring him to justice, then perhaps the Hobgoblin Empire will see reason!
Me: What about the bread route?
Cleverbot: Erm, cantaloupe.
Me: Yes! Thank you!
Cleverbot: You're welcome.
