Twenty years ago, you might have unknowingly caught a glimpse of our future president. When Barack Obama was 29, he filmed a “Black History Minute” for TBS. Disappointingly, he looks almost exactly the same as he does now, except that his hair is slightly longer and it isn’t grey. Of course, there are no videos of Obama during his wild undergraduate years because he was busy hanging out in Pakistan and dreaming that one day we’d invent a simple way to splice him into family photos.
