Larry King breathes new life into his career (with minty freshness!)

It is distinctly possible that one of TV's most legendary talkers doesn't understand a relatively simple word: "no."

How else to explain the rather mystifying career choices Larry King has been making lately in his post-CNN life. The 77-year-old must simply be agreeing to every offer that comes his way.

Perhaps the CEO of breathmint-manufacturer BreathGemz has naked photos of King and his wife, Shawn Southwick-King. What other reason could there be for the pair to appear in ad (see above) for the obscure product that seems to have all the class of a 3 a.m. infomercial on deep cable.

On April 5, King turned up at a fundraiser for the Jewish organization Chabad. That wouldn't be anything too unusual considering Chabad has pretty strong ties with a range of Jewish celebrities here in Los Angeles. But the event King attended was in the media mecca of St. Petersburg, Fla.

Perhaps the highlight of the week came the next night on Conan O'Brien's TBS late-night show, where King made a cameo. Which is great if he wasn't poking fun at himself by agreeing to appear in a skit in which he was hosting a show from the rafters of O'Brien's set. See the video here.

Up next: He's agree to sit in for Tavis Smiley on Thursday and Friday to guest-host the PBS show. Only Smiley will be there, too; King has agreed to turn the tables on the host and make Smiley the guest on his own show.

Repeat after me, Larry: "Nnnnnnnnooooooo."
