Anti Rape Condom
Over 30,000 Rape-Axe condoms are being handed out free at South Africa's World Cup. While they won't stop rape, the condoms (worn by women) have jagged-teeth inside to tear penises up, and can only be removed by doctors.<br />
Sounds grim, but then I imagine rape isn't any fun for the woman either. The inventor, Dr Sonnet Ehlers, was inspired to create the painful condom after she met a woman who'd been raped. The woman apparently told Ehlers "if only I had teeth down there," which encouraged her to look at ways to make men regret their actions.
