Eric' cousin Penny, whom he used to tease unmercifully when they were younger, comes for a visit, and she's...grown some. All the guys are infatuated with her, much to Donna and Jackie's dismay. Jackie and Donna try to be hotter than Penny, with disasterous results. Kitty, feeling like she's not needed, wants to get a pet.

Hyde tries to teach Fez to drive but Fez damages the car and hurts Leo, who was taking a nap behind the car. While in the hospital Leo falls in love with Kitty and starts showing up at the Formans bearing gifts for her. Kelso becomes a department store model and Jackie is jealous because it's her dream to be a model. She confronts him and demands that he doesn't do it but he stands up to her and does it anyways.

Kitty joyfully announces that she's pregnant, but the reaction that she gets from Red leaves a lot to be desired. Eric and Donna continue their campaign to get Jackie and Hyde to tell the truth about their relationship to Kelso. A trip to the DMV seems to present the perfect opportunity, but Fez is the one who seizes the day rather than Hyde.
