I know I'm going to get sooo flamed for this, but I believe it's true.
Shampoo belongs with Mousse.  In the second Ranma movie (Nihao my
Concubine), they had the guys going after the girls ya know.  Well, Nabiki
was with Kuno, Akane was with Ranma, Ukyou was with Ryouga, and Shampoo was
with Mousse.  And when he was hurt, she acted like she really cared.
That's my two cents.
