The flag in Miss Hoover's classroom has 25 stars and 15 stripes.
(Lisa turns to a table with four businessmen who are sponsoring the bicentennial)
Lisa: I hope you know you're sponsoring a celebration for a murderous pirate.
Sponsor: A pirate?! Well that's hardly the image we want for Long John Silver's!
Lisa: Hi Apu! Can I put this poster in your window?
Apu: Well of course you can, you little Pixy. You are just as sweet as the Stix which bear your name.
(Apu notices Lisa's poster as she's putting up)
Apu: (Gasp) No no, no no no! Take that down! As a semi-legal immigrant, your poster could land me in a predicament as Red Hot as the candies which bear that name.
(Jebediah Springfield's coffin has just been opened, everybody gasps)
Chief Wiggum: Jebediah Springfield has been replaced with a skeleton!
Hollis Hurlbut: No, that's the skeleton of Jebediah.
Homer: You su-diddely-uck, Flanders!….Hear ye, hear ye! Ye olde town crier proclaimed crappy by all! Chooseth Homer Simpson, and he shalt rock thy world!
Chief Wiggum: Good God, he is fabulous.
Principal Skinner: Yes, he's embiggened that role with his cromulent performance.
Lisa: How about town crier? You'd be great at that.
Homer: You think so?
Bart: Well, yeah, Dad, you're a big fat loudmouth and you can walk when you have to.
Jebediah Springfield: A noble spirit "embiggens" the smallest man.
Edna: Embiggens? I never heard that word before I moved to Springfield
Ms. Hoover: I don't know why. It's a perfectly "cromulent" word.
(inside Moe's Tavern)
Moe: Barney, show 'em the exit.
Barney: There's an exit!?
Lisa: I'd like 25 copies on Goldenrod.
Lisa: 25 on Canary.
Lisa: 25 on Saffron.
Clerk: All right.
Lisa: And 25 on Paella.
Clerk: Ok, 100 yellow.
Hollis Hurlbutt: Get out! You're banned from this Historical Society. You, and your children, and your children's children! ... For three months.
Homer: Hear ye! Hear ye! What's for breakfast?
Homer: I can't understand thee.
Marge: Ugh... Ye olde toast.
Lisa: Just when I was getting over my Chester A. Arthritis.
Ralph: Can you open my milk, Mommy?
Miss Hoover: I'm not mommy, Ralph. I'm Miss Hoover.
(Bart overhears Lisa talking in her sleep)
Bart: "I want to help you, George Washington"? Even your dreams are square.
Mayor Quimby: Can't we have one meeting that doesn't end with us digging up a corpse?
Homer: I've been called a greasy thug, too. It never stops hurting. So here's what we're gonna do: We're gonna grease ourselves up real good and trash that place with a baseball bat.
Homer: Less chat, more hat!
Kearney: Those tall ships really lifted the nation's spirits after Watergate.
The words "cromulent" and "embiggen" were both coined by the writers of this episode. Although completely made up, these words have since taken on a life of their own via the Internet and other media. "Cromulent" has also appeared in the Webster's New Millennium Dictionary of English.
Ironically Donald Sutherland played the character Homer Simpson in the 1975 film "The Day of the Locust."
"Hollis" and "Hurlbut" are freshman dormitories at Harvard.
Blackboard Joke: None.
Couch Gag: The screen is divided into squares with 9 squares featuring (in this order, starting with the top left) Lisa, Marge, Grandpa, Maggie, The Living Room, Bart, Snowball, Homer, Santa's Little Helper. It is very similar to The Brady Bunch opening. They look at each other also reminiscent of The Brady Bunch. They all run to the couch, leaving grandpa snoozing in his square.
The episode ends with a special original song over the credits.
Lisa going into Moe's Tavern to tell the patrons that Jebediah Springfield was a fraud, and their reactions (mouths gaping open) is a direct allusion to the famous scene in the Mel Brooks' film The Producers showing an audience with the same reaction.
Chester A. Arthur
Lisa jokingly claims she has "Chester A. Arthritis" in the historical society. This is a reference to the twenty first president of the United States: Chester A. Arthur.
