I WISH I COULD GIVE YOU AN ANSWER. Kristine: LET ME ASK YOU THIS, WHEN IT CUTS TO JUJITSU. YOU WERE ONE OF THE FIRST -- WHAT MAKES JUJITSU SO SPECIAL? WHAT MAKES YOU LOVE THAT SPORT?

IT'S A SUCH FORM OF SELF-DEFENSE. YOU CAN'T JUST GO GET THE BELT WITH JUST JUJITSU BUT FOR SELF DEFENSE, IT'S UP THERE. THE BEST SELF-DEFENSE IN THE WORLD. Reporter: WHAT YOU WOULD LIKE TO SAY. YOU SAID CONGRATULATIONS AND THANK YOU TO THE PEOPLE. FOR YOUR FANS, YOU HAVE A LEGEND. IT WASN'T JUST HAWAI'I FOLKS. YOUR NAME, IF YOU WILL, IS SYNONYMOUS WITH UFC FIGHTING. ALL THE FANS, I'M GLAD THEY TOOK ME IN. TALKING ABOUT WORLDWIDE FANS AND HERE. AND JUST -- I'M GLAD I GOT TO PLAY A PART LIKE THAT BECAUSE I DON'T THINK ABOUT IT. I'M WALKING UNDER AND SOMEBODY IS LIKE, I STARTED DOING JUJITSU BECAUSE OF YOU. AND GOING TO INTO MMA BECAUSE OF YOU. IT MAKES ME FEEL GOOD AND I GET REAL TOUCHED WHEN PEOPLE SAY THAT.
