Because what happened is after Steve graduated, he went off to Proctor & Gamble, and then two years later he came back to Stanford. I don't know if you all know that, but he came to Stanford to the business school. And after the first year during the time he would go do a summer internship, he was asked by Bill to go up and check out Microsoft up north in Washington. So he checked it out and decided, and the rest was history. So I want to introduce this fabulous, wonderful leader who's going to sha...
