That's all, folks! After 25 years and more than 5,000 episodes, Oprah Winfrey is signing off and will air her final show today.

Details surrounding the finale have remained a secret, but the buzz is that it will be very intimate and few dry eyes are expected from viewers, staffers and Lady O herself.

“I am the most surprised of anyone that this has lasted 25 years,” Winfrey tells The New York Times. “When (Phil) Donahue had lasted 25 years and I was in the single digits, I thought, ‘That will never happen to me!' I never imagined that you could do it this long.”
