One sunny day in 2009, an old man approached the White House  from across Pennsylvania Avenue, where he'd been sitting on a  park bench.  He spoke to the Marine standing guard and said, "I would  like to go in and meet with President Hillary Clinton." The Marine replied, "Sir, Mrs. Clinton is not President  and doesn't  reside here."

The old man said, "Okay," and walked away.

The following day, the same thing happened.  The man approached the White House and again said to the same Marine, "I would like to go in and meet with  President  Hillary Clinton."  The Marine, frowning, told the man, "Sir, as I said yesterday,  Mrs. Clinton is not President and doesn't reside here."

The man thanked him and again walked away. 

The third day, it happened, yet again. After the man asked his question, the Marine, understandably agitated at this point, glared at him and said, "Sir, this is the third day in a row you have been  here asking  to speak to President Hillary Clinton. I've told you twice that she is not the President and doesn't reside here.  Is there something wrong with your hearing, or are you just so dense you can't understand simple English?"

The old man replied, "Oh, I understand you fine.  I just  love hearing your answer!"  The Marine snapped to attention, saluted, and said, "See you tomorrow."
