Remember that commercial from the ‘80s where two unsuspecting strangers bump into each other and are, like, really pissed? One hisses “You got peanut butter on my chocolate!”

Then some other dude retorts, “Well, you got chocolate on my peanut butter!”

A nanosecond later both say, “Mmmm, that’s good!”

It took a bit of time for the pair to warm up to the idea. But they totally did.

Fast forward to ’09 and I’m feeling pretty “mmm-mmm fab” myself about a new mashup that might prompt some people, particularly women, to scratch their heads: Twitter + mammogram = Twammogram, or live-tweeting one’s mammogram.

I’ll give you a second.

Ready? The awesome idea is the brainchild of two tweeps (Twitter peeps) who live in different parts of the country, have never met in person but have a “two-peas-in-a-pod” Twitter/Facebook bond. The #Twammogram concept has caught on with global followers of the women, Misha Niklewicz, of Napa Valley, California, and Laura Methvin of Tallahassee, Florida -- and spread way beyond their base.

(Full disclosure alert: I have been tweeps with Methvin since I began tweeting back in February and I recently began to follow Niklewicz.)

@MishaRN and @WeeLaura, their respective Twitter usernames, say they’ve heard from many women who a) were scared to get their mammograms b) wanted to undergo the procedure but were uninsured or c) hadn’t thought about getting any dang mammogram until Misha and Laura began making their appointments.

Laura, 42, who’s a singer/songwriter by night, legal eagle by day, is set to live-tweet her mammogram Oct. 23, but she has already begun her multi-media preparations: http://virtualista.posterous.com/before-the-zombie-apocalypse-there-will-betwa

“Yeah, I'm live-tweeting my mammogram. All in the name of raising awareness during Breast Cancer Awareness Month in October,” Laura writes in her LOL blog.. “BONUS: I'm promising to shoot a shirtless video if Ashton Kutcher or Stephen Colbert signs on to support the campaign.”

Misha, 40, a labor and delivery nurse, had her first ever mammogram Thursday, which you can read about here in her blog http://laugh-rant-snort.blogspot.com/2009/10/yes-i-blogged-my-mammogram.html.

Her insight showed no boundaries including a photo of her squished tata in the mammogram machine.

"It hardly took anytime at all. In fact, it would have gone faster, but I was tweeting and snapping photos. My mammographer was awesome. She thought it was a little weird that I was taking photos and texting the whole time- but she went with it!," she writes in her blog.

"Colleen is the rockingest boob smusher! #twammogram."

I spoke to Laura and Misha Wednesday, before either of their mammograms.

“We were two goofballs trying to get our friends on Twitter to get mammograms,” during Breast Cancer Awareness Month, Misha said, of the initial Facebook exchange on Monday, Oct. 5. It “grew expendentially” throughout the day and then got a celebrity boost from Oscar-winning actress Marlee Matlin, who retweeted (forwarded) it to her 25,000-plus followers, Misha said. Then ABC News White House correspondent Jake Tapper also passed it along to his 28,600 fans.

Such celeb/media personality re-tweets are home runs in the Twitterverse.

Laura has reveled in the response.

“It’s hugely gratifying better than a real dopamine rush,” she said. “And it’ll be a super big bonus of helping somebody who needs one.

So, to get inspired, follow @Twammogram on Twitter. Or, if you decide to live-tweet your mammogram experience, use the hashtag #Twammogram to search for the subject.
