He is a water sommelier. That's a real profession now. He is also the author of a book titled "The World of Water," which is basically the water version of one of those wine or beer tasting books. But most notably he oversees the beverage program at Ray's and Stark Bar in Los Angeles. And by "beverages," I mean water. The menu is 45 loving pages long and is all water, sorted by country. Each entry on the menu includes the number of total dissolved solids and how much salt, magnesium and calcium is contained within that particular bottle of water.

Fascinating. Oh, and that bottle of Berg () in the picture? That'll be $20, thanks.
