The extra bedroom Homer built on the Simpsons' house in from "Lisa's Wedding" is still there.
In "Lisa's Wedding" Moe has only one eye- here he has two of them.
When Bart says, "So I'm the President's no-good brother. Moochie, moochie!", the captioning said, "In the words of the late, great Charro, 'Moochie, moochie'!" (probably changed for fear of a lawsuit).
Bart says the Zip code for DC is 30452, it's really 20041. 30452 is really the Zip code for Register, GA.
The Park ranger's class ring is on the LEFT hand but when the mosquitos take it, it's on the RIGHT hand instead.
Unless something weird happens in the next thirty years, 2030 isn't going to be an election year. In the United States; elections are held in the years divisible by four. Also, this episode presumably takes place in the year 2030, but U.S. presidents aren't sworn in on even-numbered years because inauguration takes place in January of the year *after* the election, which will always be an odd-numbered year. In other words, Lisa wouldn't be president in the year 2030.
When Homer says, "Let's respect the way of the Indian", the lip-sync and closed captioning says "Let's respect the way of the Red Man". (unless this was an edit done for syndicated versions and rebroadcasts)
Bart had the SAME voice as an adult as he does as a child; yet in "Lisa's Wedding," Cartwright gave him an older voice.
The Washington Monument is not that close to the White House.
When Bart plugged in his guitar and everyone was reacting to it, Carl is seen in the audience but he is yellow-skinned instead of brown.
When Bart sings the Jimmy Buffet rip-off, the closed captioning and lip-sync reads "Wasting away again in Daquiritaville" while Nancy Cartwright (the voice of Bart Simpson) said, "Wasted once more in Daquiritaville".

Homer: She knows what time dinner is.
Flanders: Hi Bart. How much this time?
Bart: Dude, you got me all wrong.

Bart: My little one . . .
President Lisa: Oh, Bart could screw everything up.
Secret Service Agent Kearney: You want him…
Lisa: No, just keep him out of my hair.
Kearney: Out of your hair…with extreme severity?
Kearney: Come on, every president gets three secret murders. If you don't use them by the end of the term, then pfft, they're gone.
Lisa: My Administration will focus on the three R's. Reading, writing, and refilling the ocean.
(Bart and Ralph are locked out and evicted)
Bart: Ohh, I had half a beer in there! And "Bewitched" is on!
Homer: This virtual fudge tastes like crap.
Marge: It's not half as good as cyber fudge.
Homer: What a bleak and horrible future we live in!
Bart: Don't you mean "present"?
Homer: Right, right. Present. Anyway, can I get you some 'Soylent Green'?
Bart: I figured I could be your, like, co-president.
Lisa: Co-president? Are you crazy?
Bart: Mom! Lisa won't share!
Marge: Be nice to your brother, Lisa!
Indian Casino Owner (on phone): Your linen service has broken many promises to us. Laundry bill soar like eagle!

Bart: What happened to you, China? You used to be cool..
Chinese Guy: Hey China's still cool! You pay later! Later!
Lisa: Bart, you do not send a billion dollar helicopter to pick up your drinking buddy!

Homer: I'm still cool!
Bart: Nah! You've changed, man.
Homer: Well, I do have this robotic prostate, but you can't see it! Oh you can.
(to the tune of "Day-O")
Bart: Daylight come and you wanta my tape.
Ralph: Tape, he say ta-a-ape-oh
Bart: Post Office Box 3 - 0 - 4 - 5 - 2.
(to the tune of "Escape (The Pina Colada Song)")
Bart: If you like refund adjustments,
And the music I play.
Send a check to my friend Ralph,
And he'll send you a tape.
Bart: I can't believe "Smell you later" replaced good-bye.
Indian: If you want to see your future, throw a prized item into the fire.
(Bart throws something in the fire. It pops)
Indian: Not a firecracker!
Bart: Hey, I bought it off an Indian on your reservation.
Indian: That's Crazy Talk!
Bart: No, it's true.
Indian: No, that's my brother, Crazy Talk. We're all a little worried about him.
Homer: Gold bars found by Marge: zero. Gold bars found by Homer: We'll find out.

Blackboard Joke: Non-flammable is not a challenge.
Couch Gag: The living room is a trendy nightclub and everyone gets in except Homer.
"Bart To The Future" was recently selected by Entertainment Weekly as "Worst...Episode...Ever!"
When Bart goes on TV in front of Lisa playing his guitar trying to sell his tapes, he parodies the song "Day-O", originally by Harry Belafonte.
Future Nelson is dressed like Biff Tannen from the 1989 film Back to the Future Part II.
Lisa: Lincoln didn't hide any gold in the White House.
Homer: Then what is his ghost protecting?
Guests in the White House have actually reported seeing Abraham Lincoln's ghost, although the poet Vachel Lindsay wrote that his ghost walked at midnight in his hometown of Springfield Illinois. This famous ghost covers a lot of ground. Apparently, Lincoln also had at least one supernatural experience while he was alive. He dreamed about his own assassination shortly before it happened. Of course, skeptics say that Lincoln had received several death threats during his presidency and therefore it was natural that he would dream about being killed.
Cabinet Member: We're going to have to sell them the amber waves of grain, the purple mountains' majesty and the shores of Tripoli.
"Amber waves of grain" and "Purple mountains' majesty" are lines from "America The Beautiful." "The shores of Tripoli" is a line from the Marine Corps Hymn.
The scene when Billy Carter's ghost appears as a bartender is a parody of the movie The Shining, in which Jack Nicholson has several conversations with Lloyd the ghost bartender in the ballroom of the Overlook Hotel.
Bart's song "Daquiritaville" is a parody of Jimmy Buffett's signature tune "Margaritaville," although Bart claims it is "original."
Bart to the Future is a reference to the film Back to the Future.
Willy: The shield needs more power!
Willy in the future is acting as Scotty from Star Trek, who is Scottish also.
