Swear words are sparse on the show which is really nice for a change (i.e. you hear more swear words out of little kids these days). And I was very proud of Homer for reprimanding Bart for using foul language. The reason all of this surprised me was because when I was growing up, I was never allowed to watch the Simpsons because it was a "bad show." I thought it would be similar to Family Guy, which is just a long string of poorly executed dirty jokes and insulting, stupid stunts. The only resemblance to the shows are the animation style, and that's even a stretch.
So in a word, I have gained respect for the Simpsons.
