"What's zero divided by zero?" It's a basic maths problem, right? Not when you put it to Siri. Thanks to Apple's in-built PA, the question has the internet freaking out right now, not least Breaking Bad's Aaron Paul...

Naturally, Twitter obeyed and spread the word.

If you have Siri, try it now. Her sassy response is guaranteed to make you giggle.  

If not, imagine a computerised voice offering this response and you'll see why the internet is having a moment...

“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.”

Pretty harsh, eh? No wonder Siri's brassy response has got the internet in quite a state.

She's responsible for a wave of low morale on social media...

In fact, some Siri users are not feeling very friendly towards her today...

And this meme summed up everyone's feelings beautifully...
