Lisa befriends a new student named Alex Whitney, whose mature attitude convinces Lisa's friends to be just like her. As a result, Alex and her new friends convince Skinner to host a school dance and set out to buy outfits for the dance in order to get a date. However, when Lisa joins the dance, she discovers the boys and girls at separate ends, proving to Alex that the children are not yet mature enough. Meanwhile, Homer convinces Bart to drop out of school for what he thinks to be a more promising pursuit: selling grease. However, this endeavor fails when their business only results in a scuffle with Groundskeeper Willie.
