If you were a skeleton it would have been hard to tell what sex you were. I am not surprised at all that stuff pissed him off, he gets hung up on details sometimes.

[Which is weird because Yusuke doesn't seem to think about the details, so much as react to them.]

He wears a pastel green uniform, if he thing the gel makes him look cool he'll keep doing it. Which I'm fine with, it doesn't change the fact he looks like Gon's dad.
