I don't think Tina Fey has 16 INT. She brought Jimmy Fallon to prominence, if even for a little while. Maybe it was her giving the industry the finger but since she appeared to enjoy his presence, I think not.
Haven't watch South Park in a long time but its still better than Family Guy. FG is basically a glorified version of I Love the 80s with even less writing. Take a joke that lasts 5 seconds and stretch it to a minute. You only got 22 minutes and only 14 minutes of actual material. The longer the joke is stretched out, the funnier it is, right? Throw in a few misogynistic and racist jokes in there because you want to be edgy. Cleveland is black! Make a few jokes about that. Make a joke about that time of the month, if you know what I mean. That still gives Seth the chance to have a couple more extended jokes. Maybe replicate a TV show scene. Then make another 80s reference for good measure.
People like Family Guy because they hope that some religious or feminist group somewhere is offended at the material. I wonder what would happen to the ratings show when these people realize that those groups don't really give a fuck.
