Steve Ballmer

If you look at companies with upside potential, Twitter's right there. They've established a brand in a world where it's extremely difficult to establish a brand. It's a global brand, people recognize it, people want to let you know what their Twitter handles are, etc.

There's great stuff out there, but I prefer doing a TV show, going to work every day with the same people, and a lot of stuff is not being shot in Los Angeles and I don't really want to do that because my loved ones are here.
