You know the commercial …

“The police often question him just because they find him interesting.”

“One-third of his body weight is gravitas.”

“His business card simply says ‘I’ll call you.’”

Yes, he’s the most interesting man in the world.

But he’s actually not the guy from the Dos Equis commercial. Instead, the real deal is Oracle’s (NASDAQ:ORCL) Larry Ellison.

Just take a look at his interview on CNBC yesterday. In it, he mentioned his personal credit line of $4.5 billion (backed by his stock holdings). According to Ellison: “I’ve got a line of credit just in case I go shopping and something catches my eye.”

And he has already drawn about a billion of it. Of course, he shelled out about $500 million for the Hawaiian island, Lanai. He plans to turn it into some type of Jurassic Park laboratory for sustainability. Cars will be electric, energy will come from solar, farming will be organic and drinking water will somehow come from the ocean.

Oh, and Ellison has also been on a buying binge for old-style mansions. The reason? He he wants to turn them into museums!

OK, so what’s next? Ellison says he would love to buy the National Basketball Association’s Los Angeles Lakers. Although he did mention it would be “a very expensive way to get floor seats.”
