"I still don't understand, Ran-chan.  The book says not to stick you in a pit
with a horde of angry cats and fish sausages strapped to your back, because 
it never works.  So how come you _did_ manage to learn the Cat-Fist from
that treatment after all?"

Yup.  The joke here was that the original Cat-Fist story has a gaping plot hole.

As I recall, the part about the not working was on the second page and Genma never read that far. Pity, such warnings should be placed BEFORE the technique.
