I have no idea why I was suddenly inspired to look up 'pig riding'.
Personally, I don't think it's a great idea; but I guess it's better than ending up on a plate or as a football.
Or is it? They are suck wonderful animals if treated right. I think I'd rather have (a smaller) one next to me on a couch, if we had one. (Either pig or couch, for we have neither.)
