Now we know what iPhone's Siri does when you're not asking her all your questions. She likes sports. Specifically, she likes the Tar Heels.

The interactive question-and-answer system on Apple's new iPhone 4S has enthralled its fans, who spend lots of time asking Siri random and profane questions.

But try this, early adopters: Say "Tar." Siri will respond "Heels!!!" Here's visual proof from UNC basketball blog The Rafters.

Siri wasn't as helpful with voice prompts for Carolina's competitors. Saying "wolf," "Duke" or "blue" did not produce the desired response.

This news might beg the question: Will Apple release a Carolina blue iPhone any time soon?
