Oprah Winfrey actually rehearsed for the taping of Wednesday's finale.
A source close to "The Oprah Show" says Winfrey hasn't rehearsed in years, but she came in Monday to practice her final show.
Two of the segments are a complete secret to even the crew. They were blacked out and not previewed before the 1 p.m. taping.
The final episode airs Wednesday after 25 years.
