The transvestism of the Sun and the Moon

Another obvious attempt to rank-up in Google, isn't it?
Well, what I was thinking with this post is to see how funny it is that words have different genders in different languages. Of course, there are obvious cases where the gender is, well, obvious (you would never say that Julia Roberts is an actor in any language). On the other hand, in Spanish the Sun ("el Sol") is male and the moon ("la Luna") is female as the links show. However, in German, it is exactly the other way around, "die Sonne" and "der Mond".
Right now I have managed to turn fairy tales in R-rated stories! That's the power of the Internet!
