Er - I suspect that, though this seems very funny - that the farmer in question bought the boar as a stud pig - probably paying a lot of money - therefore his sexual preferences were quite economically important!!
I would have thought that a discussion with the breeder - and perhaps a swap, would have been more reasonable? I believe most breeders would stand behind their stud stock?
I hope the homophobes here read this one - yet another example of homosexuality occurring in nature - unless they might believe that the little fella had been corrupted in pre-school?
A friend of mine bought a young bull recently, who turned out to be gay!!! The heifers were courting him shamelessly, but all he would do was call out in a love-sick manner to the young bull a few paddocks away...he was swapped with a lusty young bloke.
Sadly, I believe our gay friend is now beefsteak.
