I heard an interview on NPR once [Google tells me it was 2001] with a guy who was trying to promote pawpaws as a replacement crop for tobacco. He had all sorts of functions for the fruit and plant, I guess. Don't think he's gotten very far in his campaign... haven't heard anything of it since.

But, Google pawpaw + tobacco and there it is, along with this important tidbit:
Kentucky State U has the only full-time pawpaw research program in the world.

Gosh.

I first googled on paw paw (with a space) and came up with this nominee for an adjunct MOAB nominee:
Our paw paw who art in heaven...
