She started strong, then began to cry, then regained her composure -- and in between shameless promotion for her next season, Oprah told her audience that pulling the plug, "feels right."

"I love this show ... this show has been my life and I love it enough to know when it's time to say goodbye. 25 years feels right in my bones and my spirit. It's the perfect number, the exact right time."

And then there was this moment:

"For some of you, long time Oprah viewers, you have literally grown up with me ... we've grown together ... you had your family and you raised your children and you left a spot for me in your morning or afternoon -- depending on when the Oprah show airs in your town."
