5 - 7: Proper Condom Use

Fifth graders teach Cartman how to "milk" a dog, and when Stan tries it in front of his parents, they assume it means kids aren't learning proper sex education in school. Mr. Mackey teaches the boys, while Ms. Choksondik teaches the girls, but because the two instructors are so clueless, the kids become terrified of sex. Mr. Mackey and Ms. Choksondik find themselves attracted to each other.
