There are parallels drawn in Angels in America between God's abandonment of Heaven and Louis' abandonment of Prior.
Belize: Abandoned. Prior: Yes. Belize: I smell a motif. The man that got away. Prior: Well it occurred to me.
In Finian's Rainbow, when Finian learns Og the leprechaun came to America without a passport, he threatens to have him deported. As Og starts to flee, Finian accuses him: "You're a member of a subversive underground group takin' its orders from Dublin!"
Wicked's "What Is This Feeling?" begins with this lyric: "What is this feeling so sudden and new? I felt the moment I laid eyes on you. My pulse is rushing. My head is reeling. My face is flushing. What is this feeling fervid as a flame? Does it have a name? Yes. Loathing. Unadulterated loathing". Sorry darlings, but that isn't loathing; it's lust. Then again, they have been confirmed to have romantic interest in each other so maybe they mistook their feelings.
Stephen Schwartz (composer) did this intentionally to highlight the irony of using common phrases from love songs in a song about hate instead. It's an ironic parody.
In The Pajama Game, when Sid is trying to con Gladys out of the key to the account books (which is dangling around her neck), the dialogue makes it sound as if he's asking for the key to her chastity belt ("I'm a desperate man, and I hate to ask a cute kid like you to do me a favor, but...").
In Aida: The imprisoned Aida is alone with her captor Radames. He takes off his shirt, saying, "Do you know what's going to happen now?" Several actresses in the role play Aida as being VERY fearful that he's about to force himself on her. He instead orders her to wash his back, something that at the very least is meant to similarly degrade her, at worst, meant to symbolize a rape.
In the musical version of The Phantom of the Opera (and The Movie made from it), the song The Music of the Night could be seen as an attempted seduction. The lyrics are highly-suggestive euphemisms (The Phantom is singing about his Music and the Dark/Night, but could just as easily be substituted for sex). Christine faints towards the end of the song, so ultimately nothing happens. Not that it hasn't stopped fans from speculating otherwise—especially in the movie, where Christine is clearly not wearing her stockings when she wakes up.
Brand by Henrik Ibsen has a jarring christmas scene involving a homeless mother and her child knocking at Brand`s door, begging for clothes for her frozen child. The scene plays heavily into the legends of st. Martin and other saints, sharing their clothes with a beggar in the snow, who turns out to be Christ. It also plays in on the christmas gospel, with the mother Mary seeking shelter and giving birth (at christmas, of course) to Jesus himself. To drive the point home, Brand`s own son is dead, and his wife grieves over her dead son. But given the christmas references, it is impossible not to share with the paupers. The scene makes an anviliciousTear Jerker, because we know this is breaking Agnes completely.
In Thrill Me, "Roadster" is honestly about child murder, and not anything sexual. And if you can find a show that can say, "Feel the power of my engine," without making it about sex, you have an incredibly skilled performer.
