Don't think it wasn't intentional either.  That was the portrait shot for the Time cover, notable because apparently he's not terribly friendly about sitting for a picture & the photographer has won some awards for it.  The weird thing is - and a lot of people on other blogs noted this too - it doesn't really look like him. Some people even put for the theory that it's not even him!
