They were rolling on the episode that will air today, which Oprah dedicated to her dog that just passed away, Sophie. Unbeknownst to Oprah, her fans decided to surprise her with a picture montage for Oprah to remember Sophie by.
Oprah was so overwhelmed though, that she started sobbing uncontrollably and the producer had to actually stop tape. Poor Oprah! The episode airs today, so tune in to see if the producers end up keeping the montage, and how it's edited.
