Actually, it's not as unusual as you may think. Some folks don't know how to do
anything useful, so they get more advanced degrees instead. I know of several
folks who have multiple PhD's, not that it increases my respect for them, but it
does indicate they've completed a major piece of academic work with a minimum of
supervision.
