Jesse tells Stephanie that she must apologize for going along with her classmates in teasing Walter, a kid who wears eyeglasses, but the apology makes Walter think Stephanie loves him, and when Stephanie's friends come over to the house and see Stephanie talking to Walter, they make Stephanie a target for teasing, until Stephanie turns the tables on them, and shows them how it feels to be teased. Meanwhile, at school, D.J. has been assigned to follow and observe a person for a day, then write an essay about that person. D.J. chooses Michelle to be the subject for the essay, and on ""Wake Up, San Francisco"", Joey fills in for Becky as Danny's co-host while Becky is out of town.

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.

Teaser: Michelle and Danny record the welcome message on the new answering machine. Main Synopsis: Joey gets a chance to be "Mr. Egghead" on a TV science show called "Mr. Egghead". Stephanie and her class are the guests on Joey's tryout episode. Joey feels like Mr. Scrambled Egghead when he accidentally breaks Stephanie's nose during the taping of the show, and Stephanie and her class are scheduled to have their class picture taken on the next day. Stephanie was humiliated in her class picture last year, because the photographer snapped the picture while Stephanie was in the middle of a sneeze, but this year, Stephanie absolutely refuses to let a bandage on her nose result in yet another humiliating class picture, because she's afraid her classmates will call her "Robo-nose".
