I guess I'm somewhat of a traditionalist with that said, Kimba the White Lion was one of favourites. I also liked all Looney Tunes cartoons (the real old ones), didn't much care for the super hero stuff although I did watch one or two.
Tazmanian Devil & Road Runner were the only ones I knew that would kick Bugs Bunny's ass!. No one else could touch Bugs or catch Road Runner. As for the present, I'm into Spawn HBO. Especially, when sittin' back with Henny & Coor's Lt, surround sound, etc..., just chillin'.
OK I'm going to admit, my favourite cartoon of all time is hands down Beavis and Butthead, once every six months or so I have to break out Beavis and Butthead do America. Them boys ain't right.
I didn't forget them, they just couldn't really deal w/Bugs. Just thought of another one that picked Bugs' nerves was that dude from outer space. I think his name was Alien Life-Form or something like that. All-in-all Bugs was da man!
