My absolute childhood cartoon is the Teen Titans. Hoooollly crap, I would run to the tv at the second the show was about to start. Too bad I don't have the channel that it now plays on....
The older charatoons, Doug, Johnny Bravo, Hey Arnold and the Rugrats I watched a lot as a young kid. I watched a little of the Wild Thornberrys but it really didn't hit the top of my liking.
I didn't watch this cartoon untill earlier this year because this cartoon played in the 90's. Sadly, I wasn't a 90's kid... but I do like it a lot. Beetlejuice the cartoon.
Cartoons that I grew up with and loved along with Teen Titans was The Grim Adventures of Billy and Mandy, Courage the Cowardly Dog, Edd,Ed and Eddy and a little bit of Invader Zim. However I didn't dig down and watch Invader Zim untill mid this year. I love it!
