UNDATED (CNN) -- The latest social media craze is a pair of 80-year-old women named Frankie and Dottie. Here's how these two unassuming media mavens learn about life online.

They are charming the pants off the Internet by being clueless about it. They might not know an iPad from a Brillo pad, but Frankie Schantz and Dottie Anick took over Kraft Macaroni and Cheese social media for three days monopolizing Facebook and terrorizing Twitter.

It was a stunt designed to promote the edible icon's 75th anniversary. But old birds did manage new tweets, Dottie tweeting she always used butter to make mac and cheese and it was good.

They posted photos on Facebook of themselves at 16, both are in their mid 80s now. Fans didn't' get gooey over the mac and cheese, they got gooey over Frankie and Dottie.

But by the end of their three day social media reign, Frankie described it as mind blowing and heartwarming. She especially liked having all those nice young ad agency people hanging around her California home.

Oldsters in cyberspace are practically a trend. Betty White just took up Twitter. And remember the couple in Oregon who went viral after accidentally recorded themselves on their new laptop>

Now there are a few critics who say what's cheesy is making these two octogenarians seem clueless. "The women are being exploited" posted someone. Ridiculous says Frankie. Like mac and cheese, she says you know you love it.

That's how Dottie and Frankie feel about their voyage to cyberspace.
