Other than my many hours reading Marvel (and some DC) Comics, the happiest moments of my childhood were always Bat-Times.
I remember as a little kid in the 1970s, watching “Batman” EVERY WEEKDAY, I really, really liked her, but didn’t yet understand why! LOL! (Her abilities obviously included the skill to breathe and move in that costume. 🙂 ) After I saw Batgirl, I then decided that any episode with her in it was one of the good ones.
CNN reminds me that she was the first female superhero on television. I never thought of that, then or now!
It also took me years later to realize that Batgirl coincided with Eartha Kitt’s Catwoman! (Double score! LOL! 🙂 ) And Catwoman hated Batgirl!
