On Seinfeld during an episode of Bob Cobb wanting to be called Maestro instead of Bob, a scene went something like this...

Jerry: "Elaine, from now on, I want to be called Jerry the Great"

Elaine: "I'm not going to call you that"

Jerry: "Why not? I'm Jerry, and I'm Great!"

Personally, I don't like the idea of people bringing their professional titles outside of their own environment. In the hospital, a MD can be called Dr.., at an institution of higher learning, a PhD. can be call Dr., At the White House or on Capital hill, the Mr. Clinton can add "President" to his title; in a English place of royalty, Charles(forgot his last name) can be referred to as Prince Charles, in the courtroom, a judge is "your honor", and while on active duty, you can add your rank to your title, but outside of one's environment for which their title applies, Mr. or Ms. is all that I think is appropriate. A person with a PhD means they passed an 8-year curriculum and a Prince accomplished the act of being born...so???, you are still Mr. or Ms. to me! ...no wait...maybe I do like titles afterall...how about Supreme Prince Justin ...wow!!! ...I am now royalty! Anyone else want a title? For 10 bucks I can make you into a King or Queen. *L*
