No, Valerie Harper didn't tweet anything incendiary. This was long before there was a Twitter. It was PT: pre-Twitter.
But her comeback vehicle "Valerie" (after Emmy-winning success as Rhoda on both "The Mary Tyler Moore Show" and its spin-off "Rhoda") saw her behaving so poorly she was killed off one season in. They brought in venerable actress Sandy Duncan, renamed the show "The Hogan Family," and thanks to the considerable comedic gifts of young Jason Bateman the show went on for years.
Surely, "The Connor Family" could go the same route, no?
