You may recall the television sitcom of almost the same name, from back when we were uneducated enough to think that smart was something you were or were not, rather than - as we now understand - the result of a process of careful, and a bit prolonged, self-education . . .

Or something.

"The juvenile sea squirt wanders through the sea searching for a suitable rock or hunk of coral to cling to and make its home for life. For this task, it has a rudimentary nervous system. When it finds its spot and takes root, it doesn't need its brain anymore, so it eats it.

It's rather like getting tenure." -- Daniel Dennett
