One of my areas of linguistic interest is swearing. That means that if the Prime Minister uses naughty words, I get phone calls. And not only did Kevin Rudd make a (suspiciously calculated) slip-up on TV, but a new book claims that he’s got quite the mouth in private.

So here’s a recent interview I did with Kate from HypeFM, talking to the kids about why Mr Rudd is admired if he swears in public, but they get punished.
