Wonder Woman's Generational Identity

In my mother's generation, they grew up with Wonder Woman. In ours, we have to wonder if she's a woman.

Explanation

The joke plays on the idea that the perception of Wonder Woman's identity has changed across generations. The older generation saw her as a clear representation of a woman, while the current generation questions it. This might be about a shift in gender roles and representation or it might be just a lighthearted pun.
