How difficult is it to knock out Tito Ortiz?

Hard enough that it's only happened twice in his 14-year, 24-fight career. And his lights weren't completely shut off either time.

Chuck Liddell is the only man who's ever been able to finish "The Huntington Beach Bad Boy" in this manner but if it's going to happen again it might have to happen tonight (July 2) at UFC 132 when he takes on Ryan Bader.

"Darth" is The Ultimate Fighter (TUF) 8 winner, known mostly as a wrestler who is proficient enough in his other skills to get by.

That's cutting him a bit short though and underscoring some of his abilities ... like his knockout power -- in both hands.

Evidence of this can be seen above, as Keith Jardine made the mistake of leaving his chin out there and Bader showed how dearly one can pay for it when he's throwing his hands around.

Of course, "The Dean of Mean" has suffered from a few chinny issues of late, something that cannot be said of Ortiz. But will the storied career of the legendary Octagon warrior come to an end with Tito laying on his back and looking up at the lights?
