GG is a classic. And quite tame considering the real "filth" that is on every other channel today. Tila Tequila and her ilk spring to mind.....
It has been a favorite of mine since it came on in 1985. The show did dwell on the sexual innuendo and trip over political correctness every now and then, but it was funny stuff. It certainly didn't break any new ground by crossing some line that wasn't already crossed in the 1970's.
Like Bea Arthur said, it was a show based on the unlikely love and devotion four old women found for themselves in their golden years. She also said the situation would not ever work in real life, but it made for a hellava television show.
Estelle Getty's Sophia Petrillo, by the grace of great writing by others combined with her ability to capture the part, will be one of TV's all time top 10 characters. Sophia once said after a scolding for saying another inapproiate one-liner, "I'm old. I'm suppose to be colorful" - which sums it up nicely.
