Stephanie knows it's not easy being the middle child. The way things are going, Stephanie thinks that D.J. and Michelle are getting all of the attention. Jesse and Joey are working on a jingle until they start helping D.J. with a science project, ignoring Stephanie's request for them to watch her break a hula-hoop record. Danny is trying to videotape Michelle for "Wake Up, San Francisco", ignoring Stephanie's request for him to watch her break the hula-hoop record that she wanted Jesse and Joey to watch her break. Stephanie has had enough, and she believes that the only way she'll get out of this situation is if she is not living at home anymore, so she decides that she wants to marry her friend Harry, then the guys come to their senses and realize how they've made Stephanie feel.

Sharing a bedroom with Stephanie is driving D.J. crazy, and they end up arguing about when who is allowed in the room and when who's not. In an effort to solve the problem, Danny, Jesse, and Joey set up a courtroom kind of setting in the living room, with Danny being the "judge" and Jesse and Joey being the two "attorneys", but the guys themselves have a problem. They have bet each other as to who among them is the most athletic, and to settle the bet, they have challenged each other to a foot race on a nearby track. It becomes even more serious when Becky shows up with the "Wake Up, San Francisco" crew to tape the race, which Danny wins -- literally by a nose.
