World explorer Dan Buettner is scheduled to discuss "Unlocking the Secrets to Happiness" on two segments of ABC's "20/20" on Friday.

Would one of those secrets have anything to do with, say, dating a supermodel?

After a long pause, and with disgust in her voice, PR woman Bonnie Harris waxed humorlessly: "No comment." Isn't that what you say, I thought, when the question is unpredictable?

"I'm not sure what you're going to put in print," Harris said. Oh, probably something about a PR woman for Buettner thinking nobody knows that since 2002 he has dated Cheryl Tiegs, who looks like she could be the source of a whole lot of happiness, even for a laid-back-yoga-loving-bicycling kind of guy.

Harris' unpleasant reaction raised suspicions that there was trouble in Super-Modeldom. "It's not about who's dating whom," she said. "It's about the work he's been doing for National Geographic. For the last few years he's been visiting places around the world that they call 'blue zones.' Those places have to do with the longest-lived areas in the world, including Sardinia, Okinawa, Loma Linda [Calif.], Costa Rica. One of the things that contributes to longevity is contentment. And so this special includes some of the findings that Dan has uncovered in some of his visits around the world in terms of contentment and happiness."

Buettner also has a book called "Blue Zones" scheduled for release in March.

Apparently Harris is unacquainted with my accomplishments in smart-alecky.

Yet alarmed, I started snooping around to find out whether Dan and Cheryl were still together, knowing they would hear about it. They have such good energy together that I wish them only the best, which isn't necessarily marriage!

Buettner e-mailed Wednesday that they had just returned from a "crushingly romantic" vacation. As to my question, Buettner wrote this: "Does dating a supermodel contribute to happiness? Duh."

No meeting at B96 That Wednesday meeting between B96 and community leaders over the Paris Bennett matter discussed here Tuesday was canceled.

Sounds like the right decision, as I'm told Bennett's mom, Jamecia Bennett, would appreciate talk about this unfortunate incident ceasing.

Missteps in N.H. That was "Desperate Housewives" star James Denton, whose in-laws live here, looking somber behind former Sen. John Edwards on Tuesday night as he talked about his third-place finish in New Hampshire.

On Tuesday afternoon, I advised FM107's Lori Barghini not to order up the "Presidential BarackSTAR" T-shirt just yet. No. 1: After the Iowa victory, Sen. Barack Obama should not have boastfully averred that if he won New Hampshire, he'd be the Dems' nominee. No. 2: He should have downplayed Sen. Hillary Clinton's getting choked up by saying she's tired just like every other candidate.

Moving to the other side of the aisle: Former Gov. Mitt Romney missed an opportunity Tuesday to improve on his insensitivity image problems related to, among other things, that story about the family dog's kennel being strapped to the roof of the car during a road trip. When that little girl, was she a niece or granddaughter, came over to hold Romney's hand, he should have grabbed on and held her hand throughout his silver medal speech.

Why wouldn't a guy named Mitt know that there's nothing sweeter than a little kid grabbing your hand?

Laurie's big idea Laurie Coleman's partner is hoping they become gazillionaires with BLO & GO, the hair dryer holder.

A couple of years ago Sen. Norm Coleman's model-actor wife told me she was "working on a couple things."

Her business partner, L.A. entertainment and PR guy Anthony Turk, e-mailed me Wednesday to say: "You probably do not remember, but I told you that Laurie Coleman was working on something about three years ago and we would tell you about it when the time was right. The time is right! Check out our official website at www.BLOandGO.com and you can see our TV spot and better understand the product."

The mother of this invention was inspired by a coat hanger and necessity.

"It's cool, isn't it?" Turk said. "For years when she was modeling she'd get there and there'd be 20 girls per runway show and there are like two hair stylists. So she would get her own hair started by putting a coat hanger over the door and rigging up her blow dryer so she had two free hands. All the other models would start doing it, too."

After seeing her rig that hair dryer up while traveling with Norm, Turk said," I looked at her and I said, 'Why don't you just come up with something?' She said will you help me? We became partners, got a patent attorney and we put our team [of investors] together, and created the BLO and GO."

Bet it won't take CNBC's Donny Deutsch long to decide he needs to interview her.
