The Simpsons first, Family Guy a strong second, and all South Park up through and including the movie serve. 99% of Southpark post 2002 movie doesn't even deserve to rank fourth out of four. I'm not sure what happened the creators after such a good movie.
On a side note, the biggest surprise in this thread is who is author was not. 
The
South Park: Bigger, Longer, and Uncut movie was in 1999. The 2002 season was the Kenny-free season of
South Park, in which it contained the episodes "Jared Has Aides" and "Freak Strike".
