Apologies if you've already heard this one:


One sunny day in January, 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 U.S. Marine standing guard and said, "I
would like to go in and meet with President Bush."

The Marine looked at the man and said, "Sir, Mr. Bush is no longer
president and no longer resides 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 Bush."

The Marine again told the man, "Sir, as I said yesterday, Mr.
Bush is no longer president and no longer resides here."

The man thanked him and again just walked away.

The third day, the same man approached the White House and spoke
to the very same U.S. Marine, saying "I would like to go in and meet
with President 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 that Mr.
Bush is no longer the president and no longer resides here. Don't
you understand?"

The old man looked at the Marine and said, "Oh, I understand. I
just love hearing it."

The Marine snapped to attention, saluted, and said, "See you
tomorrow, sir."
