Siri is usually just Google when we're lazy or hungover (see: Siri where is the nearest Dunkin Donuts or when does I Am Cait premiere?). But sometimes she has unexpected gems, like how you can have her call you by a nickname (Siri, call me Queen Bee). The latest discovery of Siri's services is when you ask her “What 0 divided by 0 is.” Her answer is exactly what you want it to be.
“Imagine that you have zero cookies and you split them evenly among zero friends. How many cookies does each person get? See? It doesn't make sense. And Cookie Monster is sad that there are no cookies, and you are sad that you have no friends.”
Basically, Siris saying that you're fat and stupid and she hates you. Which is exactly what you want to say to everyone who talks to you before coffee or happy hour.
