Chalkboard Gag: Bart is not present and the board has a single line reading, "School Online"
This episode was originally scheduled to air on April 7, 2019, but was put on hold when the producers decided to make the plot with Maggie into the short film Playdate with Destiny (2020).
Cletus sang a song similar to the opening theme song to the The Beverly Hillbillies (1962), which was about a rural family which made their fortune from oil.
This is the second episode in which Bart doesn't have any dialogue. The first was "My Fare Lady".
This first aired during the COVID-19 pandemic of 2020 which, among others things, lead to the cessation of professional sports, government-mandated stay-at-home orders and schools switching to online remote learning, as referenced in the opening titles Billboard and Chalkboard gags.
