We're still not over all the little tricks Cortana is capable of doing. At launch we compiled a ton of questions you could ask the Windows Phone AI in order to get snarky and funny responses. That list has grown overtime as Microsoft adds more and more phrases to her repertoire. We know she'll give a funny response when you ask her "What does the fox say?", but what happens when you ask for other animals?
Cortana's animal impressions are entertaining. Try asking her what the following animals say:
Ask like this: What does the ___ say?
You'll get some great responses from her. Find any other animals she impersonates? List them below. To our knowledge, this is a new Cortana trick that was discovered a few days ago (props to @energizedtech).
Thanks for the tip Saad!
