Trivia : Why is Patin fish special?

I think most of us have tasted Patin Fish before, which
looked a little bit like Cat Fish but it's diffent.

So yesterday while at lunch my good friend ask me.
" Ok Kai Hong, as a Malaysian please tell us why
Patin fish is special?"

I was :" Errr. because it tastes good?"

" Wrong !! Stupiak !!"

" Because Patin Fish could only be found in Malaysia
and not other parts of the world. "

I see I see...

I continued eating.
