That's the second one. That other little kid was introduced in that one, Kimi or something like that.

The Simpsons was innovative, fresh and intelligent - 10 years ago. Family Guy has never been any of those things and is fairly patchy, but in a good episode you're looking to get a fair few genuine belly laughs. South Park has been incredibly consistent, and it is interesting to see how it has altered from irrelevant and crass to important and satirical.

South Park by a fair distance.

I love the satire but I also miss the old episodes that weren't really about anything political, so it's a treat when they put out the occasional episode that is just some character's random adventure.

Wolf pretty much summed it up. Southpark rarely has moments I don't like, Family Guy often does but can sometimes be rally funny, and Simpsons... well I haven't watched many episodes but I've seen some old ones and they are clever. My favorite is the one where Homer thinks he's going to die because the sushi he ate was improperly cut.

In my eyes South Park really isn't that creative, every once in a while there's a good episode but Family Guy delivers every episode and has a really witty sense of humor.

Family Guy is written by manatees.

I wouldn't really call it witty... South Park is witty. Sharp and cerebral. Family Guy is more or less entirely devoid of plot and relies on random and incoherent short-sketches dotted throughout its episodes. American Dad has basically exactly the same humour as Family Guy, but because its writers are relying on one central theme per episode it ends up nowhere near as funny as Family Guy often is.

South Park is now more or less entirely satirical and in my opinion remains the only intelligent viewing out of the three. I watched an old episode of The Simpsons recently, the one where they adopt Santa's Little Helper from the race track, and I forgot just how down-to-earth and rooted in reality it once was. The main draw of The Simpsons was that it portrayed how real life was but in cartoon form, now it's trying too hard to follow in the erratic footsteps of Family Guy and it's looking all the worse for it.

Hehehe I love that episode(s)

That is not at all a bad thing, that's just it's style of humor.

It worked for Monty Python didn't it?

Well The Simpsons at it's prime was extremely satirical, witty and well written. I think the newer episodes are just ok, but I do agree that the show is losing some of the things that made it so great to begin with.

Also, Fox has pretty much ruined their sunday night lineup, nothing against Seth but does he really need THREE shows? Even though I like Cleveland as a character I don't really have high expectations for another McFarelane project.

I think Mike Judge made a horrible mistake by quitting King of the Hill just to do The Goode Family which was spectacularly unfunny and deservedly canceled. Sure KOTH may have been past it's peak, but it's cancelation was in vain. :(

Remember when the Fox lineup was Simpsons/Futurama/Family Guy/King of the Hill?

That was the best lineup ever.

South Park had a run from about season 3 to season 9 or 10 that remains my favorite stretch of TV episodes ever. Yeah, it was really crude for it's first season or so, but in season 2 you could see the potential for what was to come. After that, there really wasn't more than a handful of episodes that were bad until the time A.C. (after Chef). It was just the right mix of shock humor, story telling, satirical genius, and character development. Nobody creates characters like South Park.

Family Guy isn't something I tune into every week, but it's hard to not laugh when you watch an episode.

The Simpsons, like South Park, had a stretch in the early-to-mid 90s when it was seemingly on top of the world.

Personally, I just prefer the sharp satirical comedy of South Park over the slapstick of Family Guy or the story telling of The Simpsons...
