It may only have a tenuous link to family law, but I had to laugh at this, found on Geekologie. At Certified Virgin you can prove your virginity by obtaining a Certificate of Virginity. As the site says: "Whether you are a virgin, feel like a virgin, or want to be a virgin again, getting a virginity certificate is probably the easiest way to go." Who could argue with that?
Part of all proceeds will be going to aids research.
