I've only seen hher say that in fanfics... if it's in the manga, please
remind me... -_-  I think that Shampoo's just too stupid to figure out
that Ranma doesn't love her.

She Has A Mind Proportion Of 0

Sounds about right... I think her brain is a little piece of a rock in
her skull...

"Shampoo shook her empty head. It rattled."

I remember the first time I read that sentence.  I had to go lie
down for a while, I was giggling so hard.

But, I also like Richard Lawson's portrayal of an intelligent
Shampoo.  It depends on the writing, I guess.
