Simpsons, Family Guy,South Park or American Dad? Which is the best show n why?

Original Simpsons was the best, but it's past its prime. They've run out of good story lines and it's now just a shadow of its former self.
South Park relies too heavily on being profane and shocking. Not really haha funny.
I can't stand American Dad. It's Fox's half-ditch effort at creating a new Simpsons/Family Guy/Futurama type show that just failed miserably.

My favorite of the four is Family Guy. It's clever, random, and amusing.

Futurama is better than Family Guy, though.

Family Guy is the best because it has intellectual jokes and everyone can understand the crazy family aspect of the show. Also, did anyone see the Star Wars episode? Hilarious!

Simpsons- Most Interesting
Family- Most Funny
American Dad- Weird
South Park- Classic Bad Mouth Bad Asses

They're all great as far as innuendo goes...but I think Family Guy is the best just because of all the different angles...talking dog who's smarter than the family, infant bent on world domination, the paraplegic hero with a pregnant wife...it's just FUNNY!

South Park!! Love the characters and the plots.

of those four i liek south park and simpsons. but of those two south park is definately my favorite. i love that show because one, its funny. and two, just because it goes past the limits and makes an episode about anything or anyone.
