In season 2 when Nancy joined the cast, the girls often swore at themselves when they would mess up a line or make a mistake. Charlotte Rae would sometimes get annoyed at them and scold them for swearing. Sometimes lines with curse words would work their way into the scripts little by little; but only words like "hell" or "damn" could be used on the show. In the episode "Next Door" the script called for Mrs. Garrett to say the word "hell" while shouting at Jo. It took her a lot or practice to get it just right. They did the scene about 20 times because Nancy could not stop laughing at Charlotte when she would get to the word 'hell'. And then when Nancy finally got it down, Lisa would laugh. They had to change the script so that Blair would leave the room. After that episode Charlotte no longer gave the girls grief about the girls swearing.
