When Bart and Lisa discover Marge's diploma from Springfield University, Marge reveals that she had attended the university back when she and Homer had first started dating. In a flash back, Homer gives up his dreams of becoming a musician and takes a job at his father's laser tag warehouse to support Marge attending Springfield University. However, when Marge finds herself attracted to an offbeat professor named Professor August, Homer decides he has had enough of Marge's wandering eye. Homer instead focuses his emotions on his music, inventing a new sound called "grunge." As Marge continues to date the pretentious professor, Homer becomes the hottest grunge artist around, as evidenced by Weird Al's parody of his music. But when Marge sees a special news report on MTV with Kurt Loder announcing that Homer's band, Sadgasm, has broken up and that Homer is holed-up in a mansion hopelessly addicted to drugs, Marge must choose between her new life and her old love.
