When the Birds of Prey TV came out I had no idea it had anything to do with Batman. So, I never watched it. It was on really late and I think it was on against a show I actually liked. It might have been against wrestling. The only reason I know about the show is the aforementioned cameo of Mark Hamill as Live Action Joker(voiceover)
I think I only found out it related to batman several years later.
my fandom of Batman springs from the cartoons, the 66 tv show, the movies, and a small small number of comics. I'm a Batman fan, but really I read Spider-man.
