Yeah, Super Cow, haha. Cow & Chicken, Dexter's LAboratory, Two Stupid Dogs, Freakazoid, Johnny Bravo!! Those were some of Cartoon Network's greats, in my opinion.
And yeah, I also watched All That, that was right up there with The Adventures of Pete & Pete, Kenan & Kel Show, Are You Afraid of the Dark...ahh, so many great shows. And cartoons, Doug, Hey Arnold, Rugrats, I could go on forever remembering shows I used to watch, haha.
And I've tried watching Jonny Test, I just don't like it much. It seems pretty boring, but that's just my tastes.
