This comedy, which premiered in 1967 (a very good year, since it was the year I was born!) starred Eve Arden and Kaye Ballard, as, respectively, Eve Hubbard and Kaye Buell.
Eve and Kaye are next-door neighbors, and their children (played by Jerry Fogel and Deborah Walley) marry each other. Try as they might, Eve and Kaye (the characters, not the actresses) can’t help but meddle in the lives of their newlywed kids. Herbert Rudley and Roger C. Carmel played Eve and Kaye’s frustrated husbands.
Executive producer of the show was “I Love Lucy’s” Desi Arnaz. Arnaz not only produced the show, but also made appearances on it as Raphael del Gado. His son, Desi Arnaz Jr. also made some appearances on “The Mothers-in-Law.”
What I remember most about this show were Kaye’s gestures when she was upset or angry.
