O.K., here's an inane product.. a powered "hula" chair.

Purported to energize you, it apparently rotates your butt for you.

At only 200.00, what a deal!!!

Or...try the alternative...a bar stool at your local bar, where you can turn your OWN rear end, plus enjoy a beverage or two with the 200 bucks you just saved.

Here's the site if you just have to have one.
