"Sir, how many degrees will be enough for me to have?" "The more the merrier."

P.S. I feel glad that universities haven't made postdoc an academic degree yet(?). If one day that happens, what degree should a professor or academic researcher with, say, twenty years of research work under his belt, be entitled to? Assume that he wants to leave the ivory tower for the real world and work in it, can he claim that he has a post-post-postdoc degree? :-)
