Mrs. McGee is Rudy’s teacher in season six of The Cosby Show. She has appeared in three episodes of that season of the show. She is played by Elaine Stritch.
The three episodes that Mrs. McGee appeared in are "Shall We Dance?", "Cliff la Dolce", and "Mr. Sandman".
In her first appearance, "Shall We Dance?", she taught her students lessons in manners. In the first lesson, she taught them how to pass bread at the dinner table. In the second lesson, she had Kenny take part in a pretend phone call to demonstrate to the class what they should do when talking on the phone. In the third and final lesson, she had the students have a dance, having Rudy paired up with Clarence after she broke up a fight between the two after class the day before. She also offered to dance with Kenny after all the girls in the class had been partnered up.
In her second appearance, "Cliff la Dolce", she had her students write a paper on Valley Forge, and had Kenny stay after class for not taking the assignment seriously, having ended his paper with "I would write more, but I don’t have to. It’s all in my history book." As a result, the teacher told Kenny to rewrite his paper and have it on her desk first thing the next day. After Kenny left, Mrs. McGee was visited by Cliff, who called her on the phone the day before to have a meeting with her so they could talk about Rudy’s troubles with her friends. During the meeting, Mrs. McGee figured that Clair was out of town, since his wife was out of town when he came to the school to see the teacher about Vanessa and Denise years prior. Mrs. McGee went on to tell Cliff that children Rudy’s age behaved strangely, and she advised him to "step back and let it pass". Afterwards, she read to him Rudy’s paper and let him know that she knew that he wrote the paper for his daughter due to phrases such as "ubiquitous melancholy" and "downtrodden warriors" being used in it. As a result of this, the teacher had the doctor write lines on the chalkboard, a punishment that she took seriously but he didn’t. She then asked him to walk her to her car.
In her third and final appearance, "Mr. Sandman", she called Cliff and Clair, telling them that she paired Rudy with George Thompson, a classmate of the Huxtable daughter’s who was very talented in dancing, for an assignment as part of a project on life in the 1920s, telling the parents that the girl was doing nothing, but she was very talented, and could dance as good as George if she applied herself and worked hard. Later in the episode, the teacher called Cliff again, telling him that Mr. Sims told her how well Rudy did in her extra dance lessons, and that the doctor danced at the dance teacher’s place, as well. The call ended after Cliff thanked Mrs. McGee for caring for Rudy and the teacher told the doctor that she was very proud of his daughter.
