um...actually, not classic...DBZ is fairly new...90s, i believe, though it's hard to tell from the animation. Ranma's older, i think
i thought of a couple of others.

Project A-Ko
i think 3x3 Eyes is 70s or 80s
Ah! My Goddess
Bastard! is a pretty old one, it has an SNES game in japan
i can't remember when the Bubblegum series came out...i want to say it was 80s, but it might have been 90s
there was a movie that had like two different american titles, not sure of the japanese one. one of the american ones was Orion: The Starsailors, or something
Devil Hunter Yohko might be a classic series
Dirty Pair was pretty old too...i wouldn't recommend it to younger viewers though. there are a lot of...ahem...subtle innuendos...in it
the Dragon Quest anime has GOT to be old, considering the first game was for the NES
Evangelion would have to be pretty old. Weird Al did a song that was a parody of a Tiffany song, and the only video i've seen for it was a collection of Rei Ayanami footage

i think that's a big enough list for now
