Siri, Apple's voice assistant for iPhone and iPad that was first introduced with the iPhone 4S in 2011, is one funny virtual guy (or gal, depending on which Voice Gender you've chosen). Here, we bring you a list of 45 questions that you should try asking Siri. You might be surprised by some of the answers.

Don't forget to ask them more than once for various different results.

Update, 29 August 2015: Apple has just added another entertaining set of Siri responses, as part of the build-up to the launch of the iPhone 6s. If you activate Siri and say the phrase on the invitation - "Hey Siri, give us a hint" - then Siri will serve up a range of 'hints' about what you can expect. (In fact, if your device is plugged in and you've ticked the option to allow this feature, the "Hey Siri" part of the phrase will activate Siri automatically.)

At the moment they're not terribly informative, but some of them are quite funny. Give it a try.
