For more than a century, British Scouts have promised: "On my honor, I promise that I will do my best, to do my duty to God and to the Queen, to help other people and to keep the Scout Law."

NBC News reported Monday that "the first part of the promise (was) tweaked to read: 'I promise that I will do my best to uphold our Scout values.’ ”

Scouting officials in the U.K. said the Scout Promise has been altered before to accommodate Muslims, Hindus, Buddhists and non-citizens who are not subjects of the queen.
