Dead Fish Society was an organization that raised money and studied Coelacanth (the fish that was supposedly extinct for 400 million years till they found some off the coast of Africa).
My major professor in college told DFS he would join if they would come up with a Dead Fish Society tee shirt. They did, and he wore it all over.
I think it was less than 400 million years. :’) But even so, it’d be weird to have a reunion for the organization... and to arrange the menu...
