A Trip to Simpsons Mountain/References

Bart is correct in that Abe's story incorporated multiple TV series. The following were referenced:

• The Waltons- Family introduction, set in the Depression and ending with goodnights; Abe had a brother named Jason and was also called Abe-Boy (despite multiple references that he was already an adult in the Depression), a reference to John-Boy
• The Brady Bunch- Young Abe is called Bobby once
• Green Acres- Not only is Abe's grandma Zza-Zza Simpson supposed to be Zsa-Zsa Gabor (canonically her name is "Happy" Dinsdale and looks nothing like her), in one instance she acts like her sister Eva's character Lisa Douglas
• Leave It to Beaver- Abe tells that the world went black and white for a while and his mom calls him Theodore
• The Partridge Family- Abe's mother drives the same bus on the show and calls him Danny then they sing the theme song
• Even The Simpsons themselves:

Young Abe looks like Bart and is called that once

His sister Rube Ella Simpson looks like Lisa (despite that he had no sisters)

His baby brother Leroy Simpson also looks like Bart

Abraham Simpson, Sr. looks more like Homer than Abe's real father Orville Simpson

Olidia Simpson looks like Marge as Abe's real mother Yuma Hickman didn't

Zeke Simpson (a reference to Zeb Walton) looks more like Abe himself than Abe's real grandfather Old Tut Simpson

• Abe's oldest brother Luke Simpson looks like Luke Perry who is supposed to be Krusty's brother on the show
• Abe's oldest sister Lisa Marie Simpson looks like and is supposed to be Elvis Presley's daughter and within the story shares Lisa's full name
• The title is a reference to "A Trip to Spencer's Mountain", the basis for "The Waltons"
