In the kitchen, Danny helps Michelle learn how to record a greeting message on their new answering machine. But instead of a usual greeting, she sings "Twinkle, Twinkle, Little Star" until Danny stops her and does the proper greeting himself, after which he lets her do the "beep" that signals the beginning of a recipient's message.
Joey gets a chance to be the title character on a new TV science show called Mr. Egghead. Because he adores children, Joey is certain that he would be the ideal host for the show.
Stephanie and her classmates are the guest audience on Joey's audition show, intended to decide if he will be the replacement host. Joey feels like Mr. Scrambled Egghead when he accidentally breaks Stephanie's nose during the taping of the show, and Stephanie's class picture day is the next day.
Stephanie was humiliated in her class picture last year, because the photographer snapped the picture while she was in the middle of a sneeze. This year, Stephanie absolutely refuses to let a nose splint, that is made of metal, result in yet another humiliating class picture. She is afraid that her classmates will call her "Robo-nose." But, to alleviate the pain, there are two pictures taken: One where everyone wears Groucho glasses, and one without (the latter of which elicits applause from the studio audience).
Meanwhile, Danny and D.J. feel that they must use every trick in the book to fight a speeding ticket that Danny received. They even practice the "testimony" upstairs in D.J. and Stephanie's room.
