Favorite Shows That Pushed The Envelope

[darklinensuit]

What are some of your most beloved TV shows that hit the social taboos hard?

Some of mine include:
All In The Family
Roseanne
To a lesser extent, Murphy Brown

I have never seen Nip/Tuck.
I've seen a few episodes of Sex And The City & didn't really care for it. The brunette was the only one I liked (though I liked SJP in LA Story).
I know Maude will be a popular choice on this board, but I've seen only a couple of episodes.
