Our family recently acquired a piglet, which was found roaming the island. Needless to say, it was wild and hated being handled. To tame them, they are taken out to the ocean and repeatedly thrown into the ocean, whereupon they swim back and are thrown back out, until they are just too tired to fight. It seems to work pretty well; just two weeks later and the pig follows Amie (on the left, doing the throwing) around like a dog. It's really rather entertaining.
