I am sure there is more but that is all I can remember off hand, damn no wonder I can't seem to remember anything from my college years, The cartoons/anime, comics/manga ate up all my brain cells!!

I didn't have any favorite cartoon, since even then I found them silly.

Yet, you're a moderator on an anime forum.

First of all, there's a difference between a cartoon and an anime.

And second of all, this is a manga forum.

When I was very young, it was mostly; Postman Pat, Fireman Sam, Thomas the Tnk Engine, Tugs, Rosy & Jim, and a few other British-made shows.
A few more years later... A lot of classic Hanna Barbera stuff, like The Jetsons, The Flintstones, Catch The Pidgeon (classic!), Hong Kong Phooey, Wacky Races, Mighty Mouse, The Pinky & the Brain, Animaniacs, Popeye, Rugrats, Mighty Max, TMHT, Gargoyles, The Super Mario Show, Inspector Gadget, Tom and Jerry, general Looney Tunes. A bit after that, the likes of Kablam, Men In Black, Extreme Ghostbusters, Angry Beavers, Ed Edd n' Eddy, Johnny Bravo, Courage the Cowardly Dog (one of the best CN shows, ever!).
I'm sure I'm forgetting a load of stuff...

Yet, you're a moderator on an anime forum.

Family Guy is tasteless, and only watchable when I'm bored.

I remember liking Ren and Stimpy as kid.
