"My Fair Laddy" is the twelfth episode of the seventeenth season of the American animated television series The Simpsons.

In this episode, Lisa makes a bet with Bart that she can turn Groundskeeper Willie into a proper gentleman while Homer creates an advertising campaign for blue pants so he can buy a new pair.

When Marge picks up Bart from school and sees Willie is homeless, she offers to let him stay at their house, and he eventually accepts.

When he goes to the factory that sells them, the manager tells him that they do not make blue pants anymore due to poor sales thanks to a disastrous Super Bowl ad.

Even though he is respected by everybody, Willie soon begins to miss his old life and feels out of place working as the maître d' at a fancy restaurant; unfortunately, both his job and his shack were taken by the music teacher.

[4] Colin Jacobson of DVD Movie Guide liked the beginning of the episode but thought that it became "less consistent" when the My Fair Lady parody started.

[7] Eric Goldman, Dan Iverson, and Brian Zoromski of IGN named it the best episode of the seventeenth season, calling it a fun parody of My Fair Lady.

[1] In 2014, David Ng of the Los Angeles Times named the parody of "The Rain in Spain" as one of the five greatest musical moments in the series.
