D.J. makes such a good impression in a play at school that Jesse suggests that D.J. try out for a TV commercial -- an idea Danny is against, because Danny is afraid D.J. will only end up disappointed. Jesse takes D.J. to an audition for a cereal commercial anyway, and Stephanie tags along with them. After D.J. auditions, she and Jesse leave the room, then Stephanie starts pretending to audition while she is alone in the room. The company's president, Mr. Benton, walks in, sees Stephanie, and gives Stephanie the job. This leaves D.J. furious, and willing to do anything to sabotage Stephanie's efforts to practice for the commercial because D.J. is absolutely, positively, fed up with everyone treating Stephanie and Michelle like they're "soooooo cute" while D.J. is always treated like the ugly stepsister just because she's older than Stephanie and Michelle.
