Both classics, but by the time of those episodes, almost every episode ended up being a classic. It truly did deserve its four consecutive Emmys as Best Comedy Series.
I believe Cloris won one of her Emmys for "The Lars Affair," and I think Mary submitted "Chuckles Bites the Dust" as her Emmy submission episode that season and won for it.
BTW, Mary tried several more times for TV success: a variety show, a sitcom or two, and a dramedy, but nothing seemed to click for her. A shame because she had so much more to offer.
Rhoda began well, but I didn't think its final seasons were very good (after she and Joe split up). I loved Phyllis' first season, but when Judith Lowry passed away after season one and the show got revamped a bit, it was less funny. Lou Grant was an excellent dramatic series.
