Not the President.

One sunny day in 2008, 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 George W. Bush."
The Marine replied, "Sir, Mr. Bush is no longer President and doesn't reside here." The old man said, "Okay," and walked away.
The following day, the same man approached the White House and said to the same Marine, "I would like to go in and meet with President George W. Bush".
The Marine again told the man, "Sir, as I said yesterday, Mr. Bush is no longer President and doesn't reside here." The man thanked him and again walked away . . .
The third day, the same man approached the White House and spoke to the very same Marine, saying "I would like to go in and meet with President George W. Bush."
The Marine, understandably agitated at this point, looked at the man and said, "Sir, this is the third day in a row you have been here asking to speak to Mr. Bush. I've told you already several times that Mr. Bush is not the President anymore and doesn't reside here. Don't you understand?"
The old man answered, "Oh, I understand you fine, I just love hearing your answer!" The Marine snapped to attention, saluted, and said, "See you tomorrow"
