Have you seen these?  They mysteriously lurk at the top right of miscellaneous web pages on the Harvard Econ department web site.  Like here, look Philippe Aghion’s page has brains.  Mankiw?  brains. And there is no caption or explanation given.  I started to think that it was there as some kind of experiment like those guys in gorilla suits that run across the screen when you’re supposed to be counting basketballs?  So I am here to say that I am not blind to these brains.  And I see the word juice there.  You can’t slip anything by me.
