In the Shampoo debate, people keep mentioning that Shampoo stripped
for Ranma.  When exactly did this happen?  I remember that in the fourth
or third vol. of the manga (Viz English version) she stripped in
front of him, but only to show him that she was Jhusenkyo cursed
also.  Where does this "stripping for Ranma" come from?
