South Park, yes, but I've never seen spongejob. How about Rocky and Bullwinkle?
While I agree with the Simpsons and of course South Park, the new job I have allows me to stay home until about 8:30 instead of fighting the traffic every morning. This has allowed me to watch two of the best done, from my warped POV :), cartoons I've seen in awhile. Jimmy Neutron and Fairly Oddparents. Yes a lot of it is aimed at the kiddies watching but at least a couple of times during the show they'll make a joke only an adult could understand. Catscratch is another new one that looks good
I'd lose the Smurfs, Batman, and Teenage Mutant Ninja Turtles and add Beavis & Butthead, Tom & Jerry, and Rocky & Bullwinkle(loved Boris and Natasha) to the list.
If any cartoon deserves to be rated over South Park, it would be Looney Tunes(30's-50's, the new ones suck), not The Simpsons.
Of course, the age old debate continues: Who was hotter, Wilma or Betty? ;^)
