Credit goes to any celebrity who is willing to take hits – actual, physical hits – in the name of a good cause. The Kardashian Charity Knock Out, as it’s called, gives the highest bidder a chance to take jabs at either Khloe, Kim or Rob Kardashian – or even stepfather and Olympian Bruce Jenner, if the bidder finds the gall.

All are in training. The charity auction is set for November 3, 2009, and the highest donor will choose their celebrity opponent then. All proceeds go to The Dream Foundation. Also, Keeping Up with the Kardashians producers will tape the fight for an upcoming episode.

“My first initial thought was ‘Are you serious?’” Khloe told E! Online.  “But then I slowed my thoughts down and heard it was for charity. So I started asking questions, but I was still nervous.  I mean, who willingly wants to get hit in the face with others watching?”

There’s no telling which Kardashian will meet the business end of the winner’s punching glove. And, it may even occur that it is a Kardashian, or even the Jenner, who goes the distance. But, sibling Kourtney Kardashian won’t be participating, since she is currently with child from boyfriend Scott Disick (also set to be a possible boxing pick).

Although the upcoming fight probably won’t be anything to match the pulverizing horror of Raging Bull, Jenner, for one, may want to protect his mug. He recently underwent facial plastic surgery to correct a bad face lift from several years ago. And, of course, neither Kim nor Khloe would want to take a hit to the face that would require plastic surgery for repair. (If they do suffer a blow, however, new techniques in repairing nasal fractures could come in handy.)

Whatever happens, the charity fund gets the upper hand — and that may make it worthwhile for one of the Kardashian clan to sustain a wallop.
