"An entire crew of just girls? That must make the bathrooms really hard to get into," was the first thing that came to Usopp's mind, because Nami and Robin used the toilet on the ship far longer than any of the boys ever did.

"I've met lots of female pirates, and I know some crews that are captained by women, but I can't think of any all-female pirate crews in my world." Usopp did have to give it some thought. Reading about pirates had been a life-long hobby, after all, and he knew about quite a few different famous crews. Surely a crew of all girls would be notable enough that he'd have heard of it somehow? "There's still a few crews that only have men because of superstition, but I think most modern crews are smarter than that."
