VIDEO : Ellen DeGeneres Celebrates 20th Anniversary of Her 'Coming Out' Episode

It's been two decades since Ellen DeGeneres first said, "I'm gay," on national television. On Friday's episode of The Ellen DeGeneres Show, the 59-year-old comedian celebrated the 20th anniversary of "The Puppy" episode of her '90s sitcom, where her character came out as a lesbian. To mark the occasion, DeGeneres invited the cast of the series onto her talk show, along with Oprah Winfrey and Laura Dern, who both guest starred in the episode, and her wife, Portia de Rossi.
