known blooper. In a sketch, Candice  Bergen and Gilda Radner play extremely stupid people. Bergen plays a  character named "Fern" and Radner plays "Lisa". But she accidentally  says to Gilda Radner "Youre not too bright, are you, Fern?". Both  actresses break character and laugh but Radner quickly improvises  "You know, we all cant be as bright as Fern here." causing Bergen  to laugh hysterically through the rest of the sketch. This sketch  helped this episode to be nominated for an Emmy for Outstanding  Comedy
