This rumor is true, unfortunately.
The main reason, of course, being that the true info from the JFK assassination is hidden beneath the marble Sioux head in the main entrance. Ralph never wanted anyone to find that info, so if the Sioux nickname is changed, he plans to implode the REA.
And I heard this from the most reputable source in the land...the Easter bunny, who heard it from the Tooth Fairy, who, as we all know, tells the truth in matters such as this.
