Twitter tapped into Siri's hidden talents yesterday after a number of iPhone users asked the software to beatbox.
If you've never heard Siri bust a rhyme, here's how you do it.
Hold down your home screen button and say the words "Siri, beatbox..." and you'll hear a charming rendition of "boots and cats" - an original from Apple's software geniuses.

We realise Siri is not the best beatboxer but its effort was still appreciated on social media.
