The movie has been all over the news here in Birmingham because several seriously southern, fairly uptight Mountain Brookers were the butt of one of his jokes (the dinner party where he brought a prostitute? That's the one). A couple of them have managed to find the humor, but most of them are teddibly offended that he abused their hospitality.
That scene was priceless. They need to be able to realize they were the subject of a joke. The more they fight it, the more ridiculous they look.
