I'm the last person to defend the show's writing, but it's honestly no worse than the bawdy humor you get on Family Guy or many Adult Swim comedies. The difference, though, is those shows don't go out of their way to shoehorn the dirty jokes in. If they were at least somewhat subtle, it prolly wouldn't be so jarring.
But yeah, Travis also has a point..."September" Trejo was 35 years ago. The show was never really about intelligence. Suddenly catering to the 8th grader/frat boy crowd, on the other hand, is another story.
