- Best Known for the Fanservice: The film is remembered more for the publicity shot of Marilyn Monroe having her skirt lifted by a subway vent than any actual scene.
- Crosses the Line Twice: Helen (in a fantasy) shooting Richard to death several times in the back and twice in the stomach. With his dying breath, Richard begs for a cigarette - which leads to....
"A cigarette? You know what Dr. Murphy told you about smoking!"
- "Funny Aneurysm" Moment: A character played by Tom Ewell contemplates having an affair with a much younger woman, begins to feel tremendous guilt about his feelings toward her, and briefly entertains the thought of murdering her to stop her from "tempting" him. Kind of unfunny to begin with, but get this: forty-six years later, California Congressman Gary Condit - who looks almost exactly like Ewell - had an affair with a much younger woman and then was accused of murdering her. (Condit was eventually cleared, but it's still pretty eerie.)
- Just Here for Godzilla: Admit it guys... and some girls. There's only one scene you care about in this film.
- Memetic Mutation: Has anyone in the culture not spoofed the skirt-blowing subway grate at some point?
- Seinfeld Is Unfunny: The many elements of lascivious and edgy humor tend to get overlooked by many modern viewers, who enjoy the film for being "innocent."
- Signature Scene: The skirt-blowing scene, of course.
- Values Dissonance: The Girl mentions that she posed for an "artistic" picture (called Textures) in an issue of the photo anthology U.S. Camera. Richard has a copy of this issue on his bookshelf, so he pulls it out and he and The Girl peruse it. We are not permitted to see the photograph in question at first, and the context of the film (especially Richard's mentioning that there must have been a large, gawking crowd) implies that the photo probably shows The Girl nude. But then Richard shows off the photo again - this time to one of his clients at work - and Billy Wilder finally permits the audience to see it as well. It shows The Girl wearing a bikini. (In the mid-1950s, the bikini, which was a French invention, was banned in some parts of the United States, particularly in the Northeast.)
- Watch It for the Meme: Subverted, if you can believe it. A lot of people probably watch this movie to see the famous scene of Marilyn Monroe standing over the subway grate, but here's the thing... it's not in the film. A *version* of it can be seen, but it was re-shot on a soundstage (as opposed to on location, which is where the famous photographs come from) and edited so that her skirt is never seen above her waist.
