This reminds me of a scam a few years ago in Japan whereby some guy was selling some expensive pedigree poodles. Poodles had suddenly become a fad in Japan and lots of people were paying top dollar for them.
And the best thing about them was that they didn't eat meat or dog food (which is expensive). Instead, you just put them in your yard and they'll eat the grass.
It seems not a lot of people in that part of Japan had ever seen a sheep before.
