After it finally stops wrestling with boys, Tarvek comments on the trope.

* In ''Anime/DragonBallSuper'', Goku remarks that he appreciates his wife Chi-Chi being strong-willed, and Vegeta (whose wife Bulma is the same way) states that Saiyan men are naturally attracted to strong women, since Saiyan women were similarly strong.

* ''Fanfic/MariaCampbellOfTheAstralClocktower'': Maria spends the first twenty or so chapters under the mistaken impression that Katarina is trying to seduce her.

** Felicity ends up on the receiving end in a later episode. When Curtis first meets Felicity's mother, he's visibly confused that this [[[TheDitz ditzy blonde]] is related to the technologically gifted Felicity (keep in mind that in her very first scene, Donna is shown to be incapable of properly sending a text message). Later, he meets Felicity's father Noah, an EvilGenius notorious criminal hacker, and comments that the pairing makes Felicity's characteristics "make more sense".
