The family rides the rails to travel to Delaware, and while on the train, a hobo tells them some famous tall tales, casting them and other Simpsons characters into the stories.
- Call-Back: The family's lines at the beginning ("The Simpsons are going to Delaware") were taken from the end of "Behind the Laughter" where Homer edits together the next new episode of the show.
- False Reassurance: The hobo assuages the Simpsons' fears by telling them that he's "a singing hobo, not a stabbing hobo." He then starts singing about how much he likes to stab people with his hobo knife.
- Fan Disservice: The Hobo's requested compensation after each story was getting a sponge bath by Homer. In the last one, Homer groans at the massive amounts of glass between the hobo's toes.
- Leaning on the Fourth Wall: The family comments on how everyone is wondering where the Simpsons will go next, likely in reference to the criticism of "Thirty Minutes Over Tokyo" and the cultural stereotypes used. They then joke about the criticism by saying they are going to Delaware next, with them excitedly listing very boring things to do.
- Logo Joke: This was one of the episodes that repeated characters' lines for the Gracie Films logo.Homer: Oh boy! Buffalo testicles! *chomp*
- Not Allowed to Grow Up: Lampshaded at the chalkboard gag when Bart writes "I should not be twenty-one by now".
- The Stinger: Homer's line "Oh boy, buffalo testicles!" is heard over the Gracie Films vanity plate.
- Take That!: This Simpsons episode has this pot-shot at Delaware's supposed boring nature:Marge: I can't believe it! We won another contest!
Homer: The Simpsons are going to Delaware!
Lisa: I wanna see Wilmington!
Bart: I wanna visit a screen door factory!
- Wait a minute, this sounds kind of familiar...
- Universal-Adaptor Cast: Common whenever the show uses the Three Shorts format (outside of "Treehouse of Horror"), with classic American folk heroes portrayed by Simpsons characters.
- All of the Other Reindeer: The townspeople drag Paul out of town for always clumsily crushing everything, but then need him to save them from an oncoming meteor.Paul: When I'm crushing and killing you, you hate me. But suddenly, when I can save your life, I'm Mr. Popular?Lenny: Yep, that's pretty much it.Paul: Woo-hoo! I'm Mr. Popular!
- Anachronism Stew: While taking place in the 19th century, Paul and Babe are seen fighting Rodan in a modern metropolis. Lisa points this out, but is ignored.
- Ear Cleaning: Bunyan!Homer cleans out his ears with Marge's hair—as in, he picks her up and sticks her hair-first into his ear.
- Famous, Famous, Fictional: As Paul and Babe travel across America, they leave their mark by making the Great Smoky Mountains thanks to them smoking cigars, devastating a lush forest area into Death Valley, and also making the fictitious "Big Holes with Beer National Park" by drunkenly dancing, as well as an additional fictional moment of Paul and Babe battling Rodan.
- Historical In-Joke: The Chicago Fire of 1871 was started by Paul throwing the flaming asteroid from his pants.
- Hot Skitty-on-Wailord Action: Implied. Marge tells Bunyan!Homer that she needs to take a few more yoga classes when he hints at the possibility of sex.
- I Need A Drink: When asked by her husband how birthing a baby the size of a small building was, all Mrs Bunyan can do is ask for whiskey.
- Rump Roast: Paul gets a flaming asteroid down his pants.
- Screaming Birth: Hilariously (and horrifically) implied. When Paul's (normal-sized) father see's his giant son, he asks his wife how she took it. She weakly replies "Whiskey...please".
- Shout-Out: When Bunyan!Homer tears open and pours out the contents of a toy factory for Marge, one of the stuffed animals that falls by her side is of Binkie from creator Matt Groening's Life in Hell.
- Slipping a Mickey: Paul drinks one carriage full of beer and instantly gets knocked out cold. Moe reveals that he slipped a couple of giant pills into the beer, then remarks he's off to the barn dance while carrying a pill.
- Small Parent, Huge Child: The (inconsistent but at least 10 feet tall) Paul Bunyan is born to normal-sized parents. The audience does get to see the aftermath of his birth, which was apparently so traumatising to his mother that she needs some whiskey afterwards.
- Tummy Cushion: Marge has a romantic conversation with Paul while sitting on his belly. He doesn't mind, given their massive size difference.
- Your Size May Vary: Paul's size isn't very consistent. Lisa points this out as well.Lisa: His size seems to be really inconsistent. I mean, one minute he's ten feet tall, the next, his feet are as big as a lake.Hobo: Hey hey hey, who's the hobo here?Lisa: Just sayin'.
- While Connie is out wondering where she can find a renewable food source, she notices an apple tree which appears to be calling her name. Turns out the voice was coming from Hans Moleman, sinking in mud next to the tree.
- At the wagon train, there appears to be one living buffalo sleeping among the settlers, but it turns out to be Homer sleeping inside a buffalo-shaped bag.
- Comically Missing the Point: When Bart points the last two buffalo out he, and the settlers realize they can use them as a breeding pair to restore their food supply. All Homer sees is two more buffalo to kill and does so without a moments hesitation.
- Endangered Species: The Simpsons (now the Buffalkills) kill so many buffalo that it drives the species to extinction, and as they had taken to using buffalo as their sole food source the settlers are at risk of starvation.
- Gender Flip: The Johnny Appleseed legend is changed to the female "Connie Appleseed" to fit animal-lover Lisa into the story.
- I Ate WHAT?!: Parodied; when Connie offers her father an apple, he mistakes it for a buffalo testicle and happily chows down, but when she tells him it's an apple, he spits it out in disgust.
- Juggling Loaded Guns: Homer cleans out his gun while holding it in a dangerous position and singing, "Cleanin' my gun with the safety off, safety off, safety off..." Sure enough, he accidentally shoots a buffalo while doing it.
- Meaningful Rename: Connie changes her last name to "Appleseed," and the rest of her family change theirs to "Buffalkill."
- My God, What Have I Done?: Connie's father says this when he realizes that he's been shooting the buffalo to extinction. When his son says there are two more left, he shoots them both and repeats the line.
- No Party Like a Donner Party: With all the buffalo gone, the settlers decide they should eat Homer until Connie brings apples. Although Moe had already taken a bite out of him.
- Travel Montage: One with a map denoting Connie's travels planting apple trees (as trees pop up on the map), and the Buffalkills' journey (with buffalo skulls denoting their kills along the way.)

Tom: Powerful weak!
- Long List:Nelson: We got any food left?
