Marcia is walking around in a daze. By the flowery language she is using, Carol knows why: Marcia's in love. The object of her affection is Harvey Klinger. Mike thinks they should stay out of her love life, but Carol tries to help her get and keep the lad's attention by helping her learn about his hobby: insects. Hobby? It's Harvey's all-consuming passion. Carol's ploy works--so well that Harvey asks Marcia to go steady. When Marcia's version of 13-year-old "going steady" gets a little too serious for Carol and Mike's liking, Mike uses words straight out of Marcia and Harvey's mouths to make them realize that their feelings are not adult love.
