Along the lines of "there's nothing new under the sun"....

When I was a kid, I remember ads for fat burning machines that had a long belt that you put around your hips or waist and it jiggled you and was supposed to somehow jiggle the fat off:

Well, at the RV show, I saw the current incarnation of these machines, or what looked like them to me...

As far as I can tell, these just jiggle you from the bottom - so I guess they work the fat down into your feet and then dissolve it?

I guess everyone is looking for "something for nothing".
