Dr. Oz says Oprah is a phenomenon for many reasons, including her mothering instincts and the support she has given to millions. "Oprah, I want to thank you for being the dean of Oprah University. For teaching me the fundamentals. You taught me to let people surprise you and to serve their higher good when I did that. You taught me to be seen for who you really are—both me as a host, but also for the guests that I would bring on the stage. You taught me, by example, how you can be playful, passionate and practical all at once. And I love you for it, and I'm trying to copy you."
