A joke about the difficulty of crossing the US-mexico border. Often, people will try to get into the US by crossing in very remote locations --- here, the person has tried to sneak in by going all the way to the moon. However, the border patrol guard, the astronaut holding the American flag, has found the attempted border crosser even here, to which the person can only complement the border patrol.
