No, really. This isn't some elaborate joke with a punchline like Peat It, or Billie Sean or something, as a Jacko insider told the Mirror: "Michael is deadly serious about this idea. He loves the whole idea of leprechauns and the magic and myths of Ireland. It would cost around 300 million (pounds) to do. He's always wanted to open his own theme park and he thinks Ireland is the perfect place and it will have a leprechaun theme."

Plans for the park include rides based on Irish myths and legends, traditional music and, of course, plenty of Guinness for thirsty adults."

So they'll be selling a drink which starts off white and frothy and then gets progressively blacker, but with a white head. Interesting...
