Luigi Drives Like Crazy as the brothers head to the Riverfront Cafe and claims it's like sea turtles traveling thousands of miles on instinct. Mario is confused at where the conversation ended up.
Early on, Luigi calls the Marios' house to see if they have any messages. He has his eyes on Daisy while a message plays, where a guy fanatically tells them he's got a very huge flood, but he gives her the phone and turns it off.
Mario: Any jobs? Luigi: Uh... no.
Luigi is adorably tongue-tied in talking to Daisy for the first time. Even drifting off into tangents.
Mario: What my brother is trying to say, is he doesn't know what to say. Doesn't even know how to begin.
Iggy and Spike spend so long waiting for Daisy to come out of the restaurant that they fall asleep, then mistake Daniella for her.
Spike: I'm gonna get the girl. Iggy: That's not the girl. Spike: Yeah it is, she's wearing a disguise. I could spot her a mile away. Iggy: Of course she's wearing a disguise. She thinks she can fool us.
Lena greets Iggy and Spike with an annoyed and venom-tinged "Hello, morons", to which they sincerely and happily wave and reply "Hello!"
After the two admit they screwed up again, she snidely reminds Koopa that they're his relatives.
Iggy and Spike's stupidity.
The duo are introduced right when Spike bought some hotdogs, which he assumed were made from real dogs. When they spot Daisy, they do their best "stealth mode" tracking, which only makes them look more conspicuous because of their weird lizard movements.
Especially after they kidnap Daniella and are sent back to get it right.
Spike: We were wrong again. How many times have we got this wrong? Iggy:You've gotten it wrong five times. Spike: 0 for five. 0 for five. What percent is that? Iggy: I dunno. Let me think. (pause) Iggy: I dunno. But it's not good.
King Koopa really loves saying the word "Goomba". As soon as Toad is de-evolved it's practically all he says.
Gotta love the Goombas dancing to that elevator music.
It's even funnier when their commander catches them at it. He has the most WTH look on his face.
Later, Toad is able to distract them by playing the same song on his harmonica.
There's also the brief scene where Koopa is ordering some pizza for delivery. The teenaged clerk clearly recognizes him but treats him like any other customer, which implies by Fridge Logic that Koopa knows him and orders from there a lot (there's even a Koopa Special named after him). Think he gets the crazy bread too?
It becomes a Brick Joke when, as he orders the Goombas to move out and begin their invasion of the other dimension, he pauses to ask into a walky-talky "where's my pizza?"
Then even later as Koopa is confronting the Mario Bros. at the climax...
Walky-Talky: Sir, your pizza is here! Koopa: Not now.
This is then followed by him saying "looks like I win!" as he waves the Walky-Talky in the air, as if the arrival of his pizza is just the cherry on top of his victory he's savoring.
Walky-Talky: Sir? Koopa: What is it now?! Walky-Talky: The Goombas are dancing again! Koopa: (pissed) Deal with it!
Mario and Luigi having their mugshots taken. The police station is set up incredibly creepily (the suspects are kept in cages suspended from the ceiling, among other things), and Mario and Luigi are forcibly brought into a room, stood against the wall, and the cameras look like guns aimed at them. When the mug shot comes out, both look absolutely terrified.
Mario: Are we dead?
Seconds before that, Luigi takes a moment away from processing their unexpected predicament to note that he's grown an inch.
During the escape from the police station, the two hear a news bulletin that "aliens" are on the loose. Luigi is dismayed that they have to deal with aliens on top of everything else... until Mario points out that they're the aliens.
Luigi: We are? Oh, cool!
Hopper's deadpan delivery as he spins a globe of the alternate dimension, showing that aside from Dinohattan, it's all a giant wasteland. No wonder he wants to break into the human world.
"Ruler of all that you see. A few miserable streets, and... an endless desert."
"I'm your main man! Your Ramadam? Your can o' spam?" (Bertha clocks him) "Maybe she's a little shy."
When Bertha and Mario dance, Mario's initial attempt to get the rock involve burying his face in her ample bosom.
Bertha punches out the coatroom lady to give the Mario brothers an escape route. As the coatroom lady ratted them out earlier, it's not hard to laugh at her getting some just desserts.
During Mario's confrontation with Koopa at the end of the film, Mario pulls a Bob-omb he picked up earlier from his pocket. The people around him panic instantly and flee in terror screaming "Bob-omb, he's got a Bob-omb!" Even Koopa is afraid of it, whispering "Bob-omb?" in disbelief, and he actually starts to step back from it when Mario winds it up and sends it towards him. And then as its fuse ignites, the camera zooms in on it and there's a dramatic musical sting. All this fear and drama in response to an explosive the size of a golf ball. The fear becomes justified several minutes later when it blows up like an incendiary grenade that launches Koopa several dozen feet into the air.
Koopa has Iggy and Spike put into the Devo Chamber to evolve them and make them smarter... and when they pop out of it looking exactly the same, his stare of utter confusion is priceless. The rest of the scene is pretty good as the two suddenly demonstrate their new intelligence by indulging in Sesquipedalian Loquaciousness.
Koopa: Both of you, go to the desert! Iggy: Excuse me, excuse me. That hardly seems logical, does it? Perhaps we should stay here and formulate our own strategy. Tete-tete, inner circle, that sort of thing. King Koopa: Here's what's logical to me — If you do not return with the plumbers and the rock... I shall personally, kill you. Iggy: We're going. Spike: After you.
Mario and Luigi are hopelessly lost in the Koopahari Desert and they argue along the way.
Mario: You said the tunnel. Luigi: I did not, I said parkway! Mario: But you meant the tunnel! (gestures their surroundings)Go on, pick a direction! Any direction you like! Luigi:(Dope Slaps Mario and mocks him) Na na na na na! Mario: Hey, that looks good over there! (pointing at quicksand) That's it, let's die there!
This dialogue, while Mario and Luigi are hopelessly lost in Dinohattan.
Luigi: Excuse me, lady. Can you tell me where I am? Woman: Yeah, you're in my way! (pushed them away) Egg-suckers! Mario: Who are these people?!
The fact that after only just arriving, they're mugged by a sweet-looking old lady.
The Mario brothers feel their nightclub attire is a bit effeminate. Iggy says that's because they belonged to his ex-wife. What's funny is they do look conventionally masculine and considering Mario's body-type, you've got to wonder what Iggy's ex-wife looked like.
When Daisy introduces Mario and Luigi to her father, who's currently a de-evolved giant fungus, Luigi treats the conversation as perfectly normal and thanks him for his help. He also tries to shake his currently non-existing hand.
Angelica shouting "Hey, Mario!" as he's attempting to break the girls out silently.
Koopa calling himself "an egg-sucking son of a snake". You gotta wonder if that's seriously what he thinks of himself.
Koopa: Did I lie?
When Mario walks out of the store with bottled water.
"Everybody's got tap water! (slams the door and looks at the bottle) Three bucks."
In the extended cut, after Daisy explains that Koopa meant only she could withstand the force of the meteorite, Luigi looks at her and gives a "WHAT!?" that seems off-script.
After having de-evolved Scapelli into a chimpanzee, Koopa points at him and declares, in pure childlike glee, "Monkey!"
The Stinger shows some spokesmen for Nintendo proposing a videogame based on the adventures of...Iggy and Spike. They agree the game's title should be "The Super Koopa Cousins".
