- Of course, the famous quote, which everyone knows regardless of whether they've seen the movie, is hilarious and awesome. Roddy Piper came up with it himself.John Nada: I have come here to chew bubblegum and kick ass. And I'm all out of bubblegum.Fascinators: [Mass "Oh, Crap!"]
- The icing on the cake is immediately before speaking, Piper gives a little "Aw, fuck it" shrug.
- During the VERY long fight scene, Frank attempts to shatter a bottle to turn into a weapon; Reality Ensues and the bottle shatters completely, leaving Frank without a weapon. Roddy Piper externalizes what we were all thinking by giving a little snicker before jumping back into the melee.
- Frank's honest reaction to Nada's attempt at a Groin Attack: "YOU DIRTY MOTHERF—-"
- Frank's reaction when he turns to see Nada getting back up to fight yet again.
- "I'm gonna give you two choices. Either put on the glasses, or start eatin' that trash can!"
- And of course, the entire fact that this absurdly long, drag-out brawl is happening because Frank doesn't want to put on a pair of sunglasses. After a while you really have no choice but to bow to the absurdity. (The main point is that Frank suspects the world is fucked but he wants to remain blissfully ignorant.)
- Nada to the alien reporting on him: "Mama don't like tattle tales!"
- John's been shambling in a stupor around the city since finding the sunglasses, and is teetering on the brink of Go Mad from the Revelation. After finally seeing a News broadcast and starting to grasp the sheer scope of what's happening around him, he chuckles.John: It figures it'd be something like this.
- Nada finally having enough after one alien bumps into him, and going off on her in the middle of a store.Nada: Y'know, you look like your head fell in the cheese grater back in 1957. [she gasps, Nada points at a human] You? You're okay. [turns and points back at the alien] This one? Real fuckin' ugly!
- At the end: "What's wrong, baby?" That woman has just realized she's having sex with an alien who resembles a rotting corpse.
- Fridge Brilliance kicks in, too, when you remember that earlier in the film, someone described the human race's relationship to the aliens thusly: "We could be pets, we could be food, but all we really are is livestock." Does that mean this alien is committing the alien equivalent of bestiality? (In reality, it's more a case of colonialism, since Carpenter said and the characters say in the film that the Earth is basically a Third World country to the aliens.)
