Both are hilarious in their own way. I've been a Simpsons fan since they debuted on the Tracey Ullman show and still never miss an episode. The Family Guy kills me. Waaaay too many pop references in there to count. Sure some of the humor is sadistic and strange but hey, almost anything is funny if you approach it right.

American Dad is terrific. Very, very funny. I highly recommend it.

But for flat out laughs per episode, I still have to vote for South Park. I have not seen one episode yet that did not make me howl with laughter at least once. But then again, I love immature humor.

At 45, I think I am the worlds oldest 10 year old!!
