Brady Bunch: 70's Over view

I think that this episode is a great show for the 70's, this is because of the way people look and present themselves. What i mean is, well look at the young girls date a tall handsome blonde whom not only acts polite but meets the parents on the first date as well. He does this while being as calm and possed looking as possible. Also even though like today the brother of the young girl had gotten very upset about the thought of his sister dating a boy that took his position on the basketball team. Did you notice no one swore as well? Or anything of the sort?
