I haven't seen it in AGES, but I always loved "The Real Adventures of Jonny Quest" when I was a kid. It was just a cool show. Pretty dark too. (this is the new one, not the old one that was in the 70s or w/e)

Had a really cool opening too :) Makes me want to go watch it now actually

2 Stupid Dogs
Cartoon Planet
Dexter's Laboratory
Johnny Bravo
Justice League
Harvey Birdman: Attorney at Law
Samurai Jack
Space Ghost Coast to Coast
The Venture Bros.

Sub in The Power Puff Girls instead of the crappy Clone Wars cartoon and you have a great list there:)

Johnny Test also deserves an honorable mention.

Best cartoon? None, too many genres, to pick one. But here's some great
Jonny Quest
Thundarr The Barbarian
2 Stupid Dogs
Scooby Doo, Where are You?
[edit]
Forgot about The Flintstones

1. Powerpuff girls was mostly Craig McCracken's creation Genndy was second in command. (Yes and I loved Powerpuff Girls when I was a kid suprisingly and Foster's Home for Imaginary Friends)

2. WHY DID YOU NOT LIKE CLONE WARS 2003?!

"and tune in next week when we bring you the exciting conclusion of nothing happened again!"

"except if it's the end of the season, we'll make something happen, and then not resolve it for you for 6 months with our patent pending 'cliffhanger' technology!"

*yawn*

Sorry, I know a lot of people liked it, just thought it hit a very niche market that I didn't happen to be in.

Samurai Jack
Ed Edd n Eddy
Courage the Cowardly Dog
Grim Adventures of Billy and Mandy (CLASSIC)
Powerpuff Girls
Dexter's Laboratory
Johnny Bravo

Ed, Edd and Eddy, Adventure Time and The Venture Bros. are probably my three favorites. Used to watch a lot of them though. Courage, Powerpuff Girls, Dexter's Lab... more than I can remember. Just not as many that catch my attention these days.

I am Weasel, probably. Cow and Chicken, Dexter, Johny Bravo, The Ed(d)s are all up there.

I was terrified of Courage the Cowardly Dog, especially of that chicken from Mars D:

My list, in no particular order (and to be edited as I remember more shows):
Ed, Edd n Eddy
Dexter's Laboratory
Courage the Cowardly Dog (episode that made me cry: "Last of the Starmakers" )
Adventure Time (episodes that made me cry: "Thank You" and "I Remember You" )
Samurai Jack
Foster's Home for Imaginary Friends
Powerpuff Girls
Teen Titans
The Grim Adventures of Billy and Mandy

I am surprised no one mentions Regular Show one of the very few new cartoon network shows I liked

(Others include TDI, Ben 10 Alien Force and Ultimate Alien, and Delocated from Adult Swim which is also the only live action show I liked in Adult Swim)

I like what I've seen of it but not enough(only a couple episodes each) to list it as a fave. Same goes for Foster's.

Ed, Edd n Eddy
Dexter's Lab
Johnny Bravo
Courage the Cowardly Dog
Regular Show
Adventure Time
Samurai Jack
Powerpuff Girls
Hanna Barbara stuff (Wacky Races, Tom & Jerry etc)
Looney Tunes
I Am Weasal
Cow and Chicken
Grim & Evil (Grim Adventures of Billy & Mandy)
Pokemon

Probably loads more I've forgot and haven't seen in years

One of my favourites. Watching it on Cartoon Network right now!
