Having recently gotten the lead role in the school play titled "The Frog Prince", D.J. becomes convinced she is on the pathway to stardom after Jesse suggests to Danny that since he knows people in show business, he could try letting her audition for a commercial. Danny later tells D.J. that he called a casting director and it turns out that there is a casting audition the following week for Oat Boats cereal. He reminds her to think it over carefully before committing, as the chances of her getting it are, in his words, "very, very tiny. Microscopic." D.J. decides to press her luck and go for it anyway.
However, an unexpected turn of events causes trouble when Stephanie, who accompanies D.J. and Jesse to the audition, catches the director's eye and lands the part. Before D.J.'s audition, she was told that she had to have a picture and a résumé to land the part; however, she says that she does not have a résumé or a picture...so Stephanie sits at the table in the waiting area and quickly draws and colors a picture of D.J. for submission, stating that she did not have time for D.J.'s "hair". After it is announced that Stephanie is the new Oat Boat "spokesgirl", there is only one word all of them can say, and that is "What?!" (in order: Stephanie, D.J., and Jesse) Needless to say, D.J. is not happy about that at all. Not... one... bit.
Back home, Joey shows Danny his "seaweed protein wheat germ tonic" that he made in the blender. At first, he squirms at his "cholesterol-free" concoction/creation, but he's finally able to get it down his throat. Meanwhile, an angry D.J. storms into the kitchen, grabs a juice bottle from the fridge and slams the door shut, and opens the juice bottle with a bottle opener before angrily throwing the bottle opener back in the drawer and slamming it shut. While she's sitting at the table drowning her sorrows in juice, Danny notices her look of dismay, and that look tells him that things didn't go well at the auditions, to which she replies, "Ohhhh no." He reminds her of what he told her prior to the auditions, and that "They probably just gave the part to somebody's relative", to which she replies, "Ohhhh yeah." And we all know who that "somebody's relative" is.
When Stephanie rehearses the part in the kitchen, D.J. is consumed by jealousy when Stephanie accidentally gets the job instead. However, D.J. says that she is not jealous, just hungry, so Stephanie gives D.J. the Oat Boats cereal box to cheer her up. But D.J. gets as far as one piece when Stephanie snatches the box out of her hand and makes a break for it, forcing D.J. to give chase around the kitchen and demand the box back, but Stephanie won't yield an inch. When they reach the opposite ends of the table, not only does Stephanie accuse D.J. of being jealous, but D.J. accuses Stephanie of being a thief for stealing the part that she wanted so badly, and yells, "Give me that, Stephanie Judith!" But Stephanie replies, "No, Donna Jo Margaret!", and crawls all the way under the table, while D.J. climbs on top and crawls all the way over it until she reaches the other side, jumps down, and then crawls all the way under it until she reaches Stephanie while asking herself, "Why am I crawling?!" Once she does reach her sister, both fight for the box, which soon breaks, causing a mess, and Jesse and Joey end up stepping in to resolve the problem. They clean up the mess, put the cereal back in its stay-fresh bag, and send Stephanie out to the living room to rehearse, while they have a chat with D.J. in the basement, where she peddles away her anger on a treadmill. She wants to save them the trouble, but they still tell her that they strike out on auditions all the time, and it's all part of the gig. She mentions that sometimes they find Michelle "sooo cute", and then they find Stephanie "sooo cute"; but they never forgot about how "sooo cute" she was in "The Frog Prince" that nobody found it "sooo disgusting". However, she is still mad over Stephanie being "sooo cuter" than her that she lost out on the part.
In the living room, Stephanie makes a phone call to the Oat Boats cereal company, wanting to decline the part because the commotion is tearing the family apart. However, she's interrupted by D.J., who needs to talk to her pronto. She wants to put "Mr. Oat Boat" on hold but can't get through, leading to a "How rude!" by her (see Trivia) as she hangs up.
In the end, D.J. admits to Stephanie that she did not steal her part on purpose, and that she was right when she told D.J. that she was jealous. Stephanie admits she herself is jealous of D.J. and she follows her around and bugs her because D.J. is the smartest, prettiest, funnest girl around except when she hates her and gets mad at her. They admit that they are each other's best friend to the end, capping it all off with a hug. Then, D.J. decides to help Stephanie rehearse.
- The first time Stephanie says her recurring phrase, "How rude!"
- The second episode in a row where a Tanner stars in a commercial
- In one shot, on the cereal box top corner says "Olsen's" (probably a reference to Mary-Kate & Ashley Olsen)
- Jodie Sweetin (Stephanie) started her acting career starring in an Oscar Mayer hot dog commercial at age 4 (which caught the eye of the Full House producer(s), because of her talent for comedic acting)
- The girls call each other by their full names (Donna Jo Margaret and Stephanie Judith, respectively)
- The episode title is a take on "Brotherly Love", the nickname of the city (and literal meaning of) Philadelphia
