Gloria is amazed when she finds her mother, Edith, engrossed in a best-selling sex manual. Even more amazing is the effect that the book has on Edith. To make a long story short (without revealing too much of the plot), Gloria prevails upon Mike to relate the "new facts of life" to nonplussed traditionalist Archie Bunker. Written by Eric Tarloff, "The Joys of Sex" made its first network appearance on February 5, 1977. ~ Hal Erickson, Rovi
