When I first saw the episode years back, I actually didn't get that particular reference (I was more of a Marvel reader at the time). It's kind of hard for me to like or dislike Fifi as Zatanna, since she didn't actually do anything in the skit other than zap Hampton. I'm neutral about her.
Buster, however, turned Superman into a big self-righteous jerk. Didn't care for that, though I guess it was needed to advance the story. Bat-Duck pwns them all!
