TOP favorites? Well, huh. ...I think they're all my top favorites
Let's see how many I can remember...
Tiny Toons, Freakazoid, Dexter's Laboratory, Johnny Bravo, Cow and Chicken, Inspector Gadget, Ahh! Real Monsters, Rocko's Modern Life, Ed, Edd 'n Eddy, Ren and Stimpy, Courage the Cowardly Dog, CatDog, Angry Beavers, Adventure Time, The Marvelous Misadventures of Flapjack, Chowder (by the way, anyone who dislikes these last three shows really needs to sit down and give them a chance. As a character designer and animator, these shows are BRILLIANT), Invader Zim (though I'm no longer a HUGE fan of it), Animaniacs, SpongeBob SquarePants...and now I've hit a wall and can't remember any more. Probably missing some really obvious ones.
I've heard Regular Show is wicked awesome, but we don't have that channel
We just have the most basic cable channels. I look forward to watching it some day, though!
