Bizarre legal story of the day: Man meets woman. Man has oral sex with woman. Woman keeps the sperm, uses it to impregnate herself, then sues for child support. Man counter-sues for emotional distress and "sperm theft". Although the emotional distress claim is still active, the "sperm theft" claim was dismissed. On that point, the court decided:

...[W]hen plaintiff "delivered" his sperm, it was a gift -- an absolute and irrevocable transfer of title to property from a donor to a donee... There was no agreement that the original deposit would be returned upon request.
