Happy Days took place in a whole different era. And to Marion Ross, who played Mrs. Cunningham on the nostalgic sitcom, Hollywood today is unrecognizable.
Asked in a recent interview what she thought of Miley Cyrus's twerking routine, Ross, 85, recalled what her mother told her when she was starting out as an actress.
