Last year we were working on a rubber ducky debugging chatbot and relying a bit too heavily on StackOverflow data for conversational training data. It frequently gave sarcastic answers, especially if you asked for help concerning regular expressions.
The researchers had something online at one point, but it wasn't working when I needed the link for the story. They said they planned to fix it, but so far they haven't.
That sounds like a pretty good result. Yandex has released it's voice assistant a few months ago (wasn't big news here on HN because it's Russian-only), and one feature that separated it from all the rest was sarcasm and kind of dark humor it acquired. Wouldn't you want your chatbot to be sarcastic sometimes?
