Actually, the title isn't a Butthead-style joke:

Some will think it a romantic gesture, others will find it grisly. But one willing couple in the UK is about to get the chance, thanks to a government-funded project intended to promote awareness of the issues surrounding tissue engineering.

What chance? The chance to make wedding rings, or really any other ring-shaped jewelry, out of their own bone tissue.

Actually, I think the flutteriness of the UK ethics board and the article's author is more interesting than the article itself. Why not come up with a commercial venture to do this, if you can actually make money at it?
