Every once in a while, someone will discover an easter egg in Siri when you ask something funny. Instead of giving you a straight answer, Siri decides to be funny and give you a wacky response.
Try asking Siri “What is zero divided by zero”. The expression has no meaning since you can’t divide zero by zero.
Instead of just telling you the expression makes no sense, Siri decided to give you….
“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.”
