There are a lot of fics out there that explore the reason(s) why Ranma dresses up and acts like a girl as often as he does. In particular, why he has such access to things that girls wear, including various costumes and uniforms girls don't normally have or carry with them except under certain circumstances. Obviously, some things are easily explained with goal-oriented reasons, and other occasions are circumstantial, but other times aren't so easily explained and putting it all together can create quite a puzzle. It did for me, anyway. I mean, it's a gag manga, so why various outfits are pulled out of nowhere can otherwise be explained; but that still leaves the reason for why they're used.
So, I was wondering what you thought. We could even discuss some of the occasions where Ranma dressed up and/or acted like a girl. (Some of the options may not be exclusive, and if so choose the reason that would have the greatest influence.)
