After being pestered by Bart and Lisa, Homer reluctantly takes
the Simpsons to the Mount Splashmore water park. The park's rescue crew is forced to close the water slide ride after
Homer gets stuck inside, where the blocked section is craned off to be rescued. That night, the news media poke fun at Homer's massive size during their coverage of his mishap at the water park. After learning that he weighs , Homer vows to go on a diet and get more exercise. While Homer is looking for his weights in the attic,
Bart stumbles upon several old paintings of the drummer
Ringo Starr that
Marge had made as a high school student. Marge reveals she was scolded by her art teacher for painting Starr, on whom she had a crush. She sent a painting to Starr for his "honest opinion", but she never got a response back. After
Lisa suggests that Marge take a painting class at
Springfield Community College, she paints Homer asleep on the couch in his underwear, earning praise from her teacher, Professor Lombardo. The painting wins the college art show, earning Marge fame and newspaper headlines.
Mr. Burns asks Marge to paint his portrait for a new wing of the Springfield Art Museum. Marge agrees, although she resists Homer's plea to paint Burns as a beautiful man. While Burns is taking a shower at the Simpsons' house, Marge inadvertently sees him naked. Homer finds he has lost 21 pounds from his exercise regimen and now weighs . After Burns disparages Homer's weight and his daughters, Lisa and
Maggie, Marge throws Burns out of the house. She is ready to quit until she receives a response from Starr, who, though decades late, praises her portrait of him. Homer encourages Marge to finish the painting. Marge's painting of a naked, frail and weak Burns is unveiled at the opening of the museum wing, much to the shock of both Burns and the crowd, causing
Smithers to faint. She explains that the portrait shows that behind all of Burns' evil, he is a frail and vulnerable human being who is by extension just as beautiful as any other living creature in the world. With that in mind, the crowd praises Marge's portrait; even an impressed Burns does the same before thanking Marge for a job well done. ==Production==
