BJ Penn has had little time to dwell on losing his lightweight title belt to Frankie Edgar on Saturday night as he’s now going on a media blitz to support the release of his new biography, “BJ Penn: Why I Fight – The Belt Is Just An Accessory,” which is in stores from today.

Today Penn appeared on Fox News to discuss his book, and in an impromptu skit, Fox host Brian Kilmeade challenged him to show how he would neutralize him in a fight.

The former 155lb champ duly obliged and wrestled the 170lb reporter, and after some resistance from the host as it dawned on him that he was getting owned on live TV, Penn locked up a kimura submission while one of Kilmeade’s colleagues threw in the towel (well it was a suit jacket, but who’s counting!).

As an unsteady Kilmeade was helped to his feet his female co-host then finished off the segment with a flourish by stating, “After that Brian’s going to need some new health care, and that’s what we’re going to talk about (next)..”

Update: BJ Penn’s antics on Fox News were used on Comedy Centrals hit program, ‘The Daily Show With Jon Stewart’ last night.  Watch the video here
