Reminds me of an old joke.In 2001 This guy shows up near the White House every day at the same time and asks the Marine guard, "who is the President?" and the Marine says "George Bush". Finally the Marine asks, "why do you keep asking this same question everyday?" The fellow says "Because I'm so happy the answer is no longer William Clinton!" At which cast the Marine smiles and says "see you tomorrow."
Your joke reminds me of another funny:
A man goes to the White House and asks the Marine to see President john Kerry. The Marine turns him away and says: There is no John Kerry here. The next day same thing, the Marine says John Kerry is not the president. Day after day, it's the same thing.
After a few weeks he asks the inquisitor "What makes you think John Kerry is the president?"
He says "Nothing."
Marine says "Why do you ask every day?"
Man says "I know he's not president but i just love hearing you say it."
Marine "Not as much as I enjoy saying it! See you tomorrow."
