The Simpsons Episode 15.10 Diatribe of a Mad Housewife

Marge is inspired to write her first book, but Homer shows little interest or support because he's fixated instead on the old ambulance he's now driving around town, making house calls, etc. Annoyed by Homer's tendencies, Marge channels her anger into her writing and produces a period piece that depicts a despicable Homer-like character and his wife who longs for a Flanders-like neighbor.

The book is published, and Homer is upset when the whole town recognizes who the characters are in real-life. Homer goes to confront Flanders, but instead asks him for help on how to be a more caring husband.
