Grow Your Own Penis!
Scientists have finally done something worthwhile: they have figured out how to grow spare penises - functional penises. While transgendered people and people with erectile problems are probably the top recipients of this technology, who's to stop ladyboys from switching from men-with-implants to women-with-specially-grown dicks? What's to stop me from growing, like, twelve extra cocks on various extremities? The possibilities are endless, and the world has become a better place for it. A Brave New World...of penis excess.
