Wait, wait, WAIT...
What's wrong with that?
We've got a millenary tradition here, in Sardinia is like 5000 years that they are mating with sheep and other animals, and nothing has gone wrong, ever. If anything, more people should be doing that (kudos to the Welsh for the commitment) and UN should be recognizing the rights of the offspring. Silvio, as usual because of his generous and kind character, not long ago adopted one of such lambs, who was hanging out with a bad company (mostly corn addicted pigs) and saved him until the following Easter...
I'd say we should encourage that, basically because there will be less competition with regular mates
Also, I think a special mention goes to the Taliban for having removed human prostitution and replaced it with camels and sheep. They did say they were going to improve the social status of women, didn't they?
