The Simpsons is past it and shoulda been canned 5 years ago... AT LEAST!!!

To be brutally honest, Family Guy and American Dad are rubbish. All they do is spout pop-culture references in random situations that make no sense whatsoever. King Of The Hill is simply mediocre.

The Simpsons is, and always will be the king of tv animation. All I can say is, bring on the return of Futurama!

Homer flying a plane? Stephen Colbert and Lionel Richie guest star? Spiderpig appears? Can't get much better than that.

Family Guy reinacting Star Wars. Can't get much better than THAT. :)

clever and always hilarious, simply the best!

I agree with sy88. The Simpsons are the best animated series on TV right now. And probably always will be.
South Park is my second choice though.

OMG, "I don't watch cartoons.." is second. Wow.
