Can we get at least one story where someone mistakes Riven for a guy?

Come on, she's kinda androgynous-looking, and I'm sure some people could mistake her for a eunuch. It'd be a recipe for hilarity.

Personally, I'd have it be Kled who mistakes her for a guy, and then asks her to prove she's a woman in an old Master Roshi old-pervert manner. Then she'd punch Kled in the face for it. XD
