"Sitting on the subway today" joke

Sitting on the subway today, I glanced over at the woman beside me. I noticed that she had a Mensa button clipped on her bag. The button read:
M E N S A K O R E A

* ***
** ****
*********
*********
* * ***
* ***
* ***

I A R E A M E N S A N
All I could think was "who was the genius that approved that button?"
