Here are five of my favorites:

1) The penalty for masturbation in Indonesia is decapitation.

2) The Romans would crush a first-time rapist's gonads between two stones.

3) In Minnesota, it is illegal for any man to have sexual intercourse with a live fish.

4) Under Lebanese law, men are legally allowed to have sex with animals, but the animals must be female. Having sexual relations with a male animal is expressly forbidden.

5) In the quiet town of Connorsville, Wisconsin, it's illegal for a man to shoot off a gun when his female partner has an orgasm.

I think the NRA is currently working to overturn #5.
