Who dat say who dat?

The current controversy over who "owns" the phrase is so much malarkey.

I am old enough to remember the joke "Who dat say who dat when I say who dat?" about 65 years ago. It was a parody on black (in those days aka negro) phobias of the dark.  Sadly, Google does not easily come up with this conclusion after all these years.

To say that anyone owns that phrase is absurd. It's in the public domain.
