The show is just really stretching to try to be edgy, and is starting to repeat itself. Plus the old episodes don't stay funny as long as some other shows.
and I agree Russel: I love Family Guy but at the same time, I don't watch it often enough to have the show get old... or be sick or it...
It's funny once, and I only watch it once so...
I record all FG and American Dad and Futurama and Adult Swim automatically to my Tivo, and when I was in school, those would be my background noise when I did homework....
