Mr. Burns asks Marge to paint his portrait for a new wing of the Springfield Art Museum. Desperate to please his boss, Homer convinces Marge to agree, 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 239. After Burns disparages Homer's weight and his daughters, Lisa and Maggie, Marge throws him out of the house. She is ready to quit until Homer encourages her to finish the portrait.
