As the man-hungry Sue Ann Nivens, Betty White turned a guest role in season four into a regular cast spot and earned two Emmys. She went on to play the better known role of Rose on the hit series "Golden Girls." She hasn't stopped working since, appearing on everything from "Ally McBeal" to "Boston Legal" to the daytime soap "The Bold and the Beautiful."
At 91, she's showing no signs of slowing down. She has another hit series, "Hot in Cleveland," and is host of the practical joke show "Betty White's Off Their Rockers."
