What are some major Western Cartoons?

[Soviet Heavy]

I'm looking for some new cartoons to watch. I want to see if there are any good obscure titles that don't get shown very often.

I have watched
Spongeob
Futurama
The Simpsons
The Cleveland Show
Family Guy
American Dad
Justice League
Justice League Unlimited
Batman: TAS
The Batman
Batman Brave and the Bold
Superman TAS
Batman Beyond
Cybersix
Ed, Edd'n Eddy
Courage the Cowardly Dog
Star Wars: The Clone Wars
All the Genndy Tartakovsky Series

Can anyone recommend some other good western shows? I hear Venture Bros. and Avatar are good, but they aren't on any of my channels.

EDIT.
Please don't post any anime series. I don't mind them, but I am looking for stuff I can watch on my somewhat limited channels.

EDIT EDIT
This is also a bit of a social experiment. I was reading Onyx Oblivion's Major Anime thread, and I wanted to see if making a thread with the same structure about western cartoons could achieve the same amount of hits.

Dexter's Lab
Johnny Bravo
Powerpuff Girls (better than it sounds!)
Scooby Doo (original or bust)
Johnny Quest
Phineas and Ferb
Ben 10

Ben 10, Phineas and Ferb, and Scooby Doo are the only ones likely to still be on TV.

Megas XLR. Like Gurren Lagann, but more awesome.

EDIT: Wait, TV. Can't help there.

 

[Stealthygamer]

Transformers Cybertron (It get's good in the 3rd season, but you need to watch all of it to get it)

 

[Arkvoodle]

Exo-Squad.

 

[Zayren]

Adventure Time, now on Cartoon Network, either you love it or you hate it, from what I've seen.

Venture Bros. is really good too, on Adult Swim. I think you can watch a few episodes on their site, but it's really bad to watch chronologically or you'll miss a lot of jokes.

 

[StealthyNinja]

You could give Fairly Odd Parents a go, if only for Jorgen Von Strangle

Spoiler

The voices can be irritating however

 

[Cybele]

Samurai Jack is the only western one I've ever really cared about.
And it's awesome!

 

[Soviet Heavy]

Exo-Squad.

Was that the show with the power armored Space Marines?

 

[Harlemura]

Fairly Odd Parents?
That's the only thing I can think of that's on TV.

EDIT:
Arglbglrighytrgh ninja'd.

Unless Clone High's still on. Actually, go watch Clone High online anyway. It's, like, the best thing ever. Totally.

 

[Les Awesome]

theres robot chicken thats good for a laugh

 

[Realitycrash]

Samurai Jack is the only western one I've ever really cared about.
And it's awesome!

True, it was pretty good, but if Samurai Jack counts, then the entire selection of western anime is fair game.

Gonna go with Avatar: The Last Airbender. It's teh awesomer.

 

[Soviet Heavy]

Like I said, I haven't watched The Last Airbender, but I am looking forward to the sequel series. Steampunk Revolutionaries sound awesome.

Spectacular Spider-Man was the best Marvel comic book-based series on TV. It's almost as good as Batman and JL and JLU. Avengers and Young Justice are good so far. If you find reruns of Freakozoid, Pinky and the Brain and Animaniacs, then it's a must.
Also South Park and Archer if you like more adult stuff.

 

[retrochimp]

I'd recommend some older favorites you can download via torrents such as The Tick, Swat Kats, Clone High, and Darkwing Duck. Also, some Adult Swim cartoons are watchable (Frisky Dingo, Squidbillies), some are very good (Venture Bros., Aqua Teen Hunger Force, Sealab 2021, Home Movies, Harvey Birdman Attorney-At-Law) and some are downright genius (Metalocalypse, The Brak Show, The Boondocks, 12 oz. Mouse, Space Ghost: Coast To Coast). That ought to keep ya busy for a while.

I was so mad when they canceled Spectacular Spiderman, it was such a good series. Hell, Bender Bending Rodriguez was Sandman!

Ren & Stimpy is just awesome but quite disturbing. The writers must have been on some very bad drug trips. I would never show this to my kids, if I had any.
Pinky & The Brain is a must-watch.

 

[stiffy]

Boondocks!! Unlikely we'll get more after the 3rd season.

 

[Maxtro]

Wow, nobody's mentioned Gargoyles? That cartoon was just amazing.

For a comedy adult show check out Archer.

If you don't mind CG then Transformers: Beast Wars is really good.

Of course don't forget the original Teenage Mutant Ninja Turtles.
