One day, God took a walk with both Barack Obama and Osama bin Laden. He was hoping to sort out any differences the two had.
God gave up trying to form a compromise, so He offered each man one wish.
Barack very nicely offered the first wish to Osama. Osama said, "I'd like a giant wall built around the Middle East, so that no one can get in or out, especially America."
God granted his wish.
Obama then grinned and said, "Now fill it with water."
