I had the great privilege of working with her some years ago, on the sitcom Titus, where she played my mom. In recent years, I was shocked and saddened to learn she was the victim of a theft: "Mom's been robbed!" was what I was feeling.
Diller's aim was true, and while her targets might seem to some to be dated (the overworked housewife, for example), they still resonate. The world hasn't changed enough yet. We will always need writers and performers and comics like the late Phyllis Diller.
You'll hear a lot in the next few days about how Phyllis Diller paved the way for women in comedy, but that's not how Phyllis saw herself. "There have always been funny ladies, Steve," she told me when I interviewed her a few years ago.
