You cannot beat Valerie Harper (4-time Emmy winner), Julie Kavner (2-time Emmy winner and the voice of Marge Siimpson), and Nancy Walker (8-tiime Emmy nominee) in the same TV room. It is pure comedy genius as three ladies from the theatre conjure up the best chemistry in the history of television.

The best of the many Mary Tyler Moore spinoffs.

This is the best and most underrated series of all time. So much of great comedy comes from tragedy and this show certainly had its fair share of it. Even so, the fact that it never stopped being funny despite all of this tragedy is enough to get it on the greatness list. What a quiet gem! Anyway, Valerie Harper and Julie Kavner ("Marge Simpson") are the most believable and hilarious sister team ever.
