My personal theory is that Don Diego is a member of each and every one of the gnostic groups hidden around the world, and that invoking his own name confers the powers of that name upon he who says it. Therefore, because Don Diego is clearly a powerful leader with a willing flock, it is clear that repeating this name day after day, night after night, must result in truly awesome and exemplary powers.
I have, as a result of these findings, renamed myself DiegoDon in honor of DonDiego, and will repeat this name each and every hour of the day to anyone in my sight. I hope someday to have the same powers and abilities as DonDiego, only backwards.
