Cortana is the digital assistant on Windows 10, but you can also use Cortana on Android and your iPhone too.

She's useful for many things, such as setting reminders and doing unit conversions, but enough of the serious stuff: she's also got a good sense of humour.

Microsoft has given Cortana lots of amusing replies when you ask strange or unusual questions.

We've given just one response for each question, but Cortana actually has several responses for each so try asking the same question multiple times to hear the different answers.
