The Hamburger chain-store concession storyline seems to be an adaptation of Ray Kroc's biography, especially of how he acquired the concept from the McDonald brothers of San Bernardino, California after a chance encounter from a number of milkshake machines he sold to the family. It was dramatized in the film The Founder (2016) starring Michael Keaton.
Krustyland Character's alludes to the following personalities:
- Burger Reynolds - Burt Reynolds, Actor
- Grilly Cheese King - Billie Jean King, Tennis Player, most well-known for winning the Battle of the Sexes match on September 20, 1973, against Bobby Riggs
- Jack Pickleson - Jack Nicholson, Actor
- Patty Meltin' John - Elton John, Performance Artist
The plot is largely a parody of the HBO show Succession and even the theme music is adapted to a tone similar to the shows opening. In the episode, the company is called "Redstar" which seems to be an allusion to "Waystar Royco" from said show.

After Homer buys his insane number of Krusty burgers, he and Bart pass a "Pavilion Of Discontinued Items". In the order that they pass them (right to left), these are: Agent Orange Milkshake, Chicken Chokies, Burger In The Raw, Salmon Ellies, Racehorse Nuggets, Veal-Fed Milkshake, Not Apple Pie, and Gristle Tots. Two of the items in particular refer to the following: "Agent Orange" was a defoliant used in the Vietnam War, and which caused cancer in a number of returning veterans; "salmon ellies" seems to refer to Salmonella, a bacteria found in contaminated food. "Veal-Fed Milkshake" reinforces Lisa's statement that there was more meat in the drinks rather than the food. In the United States, horse-meat consumption is frowned upon.
