After a particularly bad movie experience, (consisting of Marge hurting his feelings,) Homer drives to a bar where he discovers a singer named Lurleen Lumpkin. Now, Colonel Homer is her manager, much to Marge's disgust and jealousy.
Homer and Marge go see a movie but Homer doesn't shut up in the theater. He eventually goes as far as to giving away the ending to the film and the audience boos him. Marge yells at him telling him nobody cares what he thinks which the audience cheers for but leaves him embarrassed. Hurt by Marge's words, Homer takes his family home and then drives off to a country bar to think about what happened when he meets a waitress named Lurleen Lumpkin who sings a song that he falls in love with. Homer returns home but can't get her song out of his head. He goes bowling and while singing Lurleen's music to his ball bowls a 280. Lenny sings "There's a Kind of Hush" to his ball to try to bowl better - a classic example of the Post Hoc fallacy. He drives back and decides to get the song recorded. It is given to the local radio station and the song is an instant success. Homer becomes Lurleen's manager, "Colonel Homer," much to Marge's objection.
Lurleen wants more from Homer than him being her manager, but Homer cares for his wife and kids and decides he made the right choice. He tells her that he can't be the man for her and only wanted to share her talents with the world. Homer explains that he loves Marge and can't think about doing something that could hurt her. Although hurt by this, Lurleen respects his decision to be with his family. Homer offers the man to be her new manager as he rushes home to be with Marge. Once home, he is able to reaffirm his love for her and gets in bed naked.
On Lurleen's last appearance on Yahoo, a country parody of Hee Haw, she sings a bluesy song and wishes both Homer and Marge nothing but the best for them.
