In the realm of business ideas this one is just plain, well, nutty.  According to this article it seems that a couple of enterprising folks out in Arizona have launched a line of jewelry that is testicular in design.  Of course their website is ballsies.com.

I was going to put a picture of one of their products here, but if I was gonna do something like that I’d reserve it for a product modeled on the fairer sex.  Sorry gals.
