While demolishing the kitchen, Homer unearths his old collection of Playdude magazines. He innocently tells Marge he kept them only for the articles, and she decides to make sure by cutting out all the nudes from the magazines. Now that they are useless, Homer throws them away (angrily saying "What man would want you now?"), but they are discovered by Bart and Milhouse. They read the articles and are greatly inspired. Using these 70s-era magazines as a model, Bart decides to renovate the Treehouse into a sort of Playboy Mansion replica, replete with James Caan.
After Homer's remodeling makes the kitchen useless, Marge hires a contractor to complete the job, and after two years and $100,000 spent the Simpsons enjoy their new kitchen. The dishes that come out of Marge's new kitchen get rave reviews and, on Ned's suggestion, she decides to enter the Auntie Ovenfresh Bakeoff with her Dessert Dogs. Recipe: Deep fried cookie dough weiner, meringue bun, cherry sauce ketchup, and caramel mustard.
She is successful and goes through to the second round of the contest. At the bakeoff, Marge encounters ruthless competition, as the chefs mock her and sabotages her cooking. Her Dessert Dogs are almost ruined by the end of the time limit, and she barely manages to make them presentable and get them to the room where the entries have to be stored. Still fuming about the behavior of the other chefs, she gains revenge by spiking the other entries with Maggie's ear medicine, much to Lisa's dismay.
Meanwhile, Chief Wiggum and other concerned parents talk with Homer about Bart's spreading the Playdude philosophy to the other children. Homer has a talk with Bart about the true facts of life, which a horrified Bart quickly shares with the other children, who are just as horrified. Homer notes "It's better they learn this now--than from their own parents, when they're old enough." Marge's cheating gets her to the finals, and Lisa confronts her. Marge retorts saying that the other chefs deserved it for the way they treated her; Lisa urges her to do the right thing. In the bakeoff finals, Marge admits to her foul play and Lisa's faith in her mother is restored. Brandine's "Alco-Hog" dish wins by default. When they are shopping at the Kwik E mart a few months later, they discover the new flour cover with Brandine Spuckler on it. When Marge expresses disappointment because it was almost her, they run into Cletus Spuckler, who is upset that Brandine has left him for James Caan, but he swears he's "gonna fix his wagon." When Caan stops at a toll booth, Cletus' friends emerge and gun him down in a scene reminiscent of the death of Sonny Corleone (Caan's character in The Godfather). However, despite being completely bullet-ridden, he opens his eyes and mutters "That's it, next time I fly."
