In the second-season premiere, after Mary Richards produces a "What's Your Sexual IQ?" documentary for the Six O'Clock News, Rhoda confesses to failing and Phyllis says that young Bess watched it. Phyllis calls on Mary to teach Bess the facts of life, but it turns out that Bess already had learned it from her friends. Meanwhile, the WJM-TV newsroom is shelled with phone calls responding to the documentary. According to Mary, more people are appalled by it than anything else. (thetvdb.com)
