Julianne (when Erica arrives late and makes a scene): Who the hell do you think you are, Oprah?
Julianne is alluding to Oprah Winfrey, the award-winning, one-person-conglomerate and host of the highest-rated talk show in American television history, The Oprah Winfrey Show (1984-2011). Considered by many to be the most influential woman in the world, she was once the world's only black billionaire.
