Mister X and Mister Y

    Everything About Fiction You Never Wanted to Know.

    A couple of gentlemen, whose last names are X and Y, exchange polite banter, in which they frequently call each other "Mister X" and "Mister Y."

    Often done by Those Two Guys or Those Two Bad Guys. (Our self-demonstrating description for Those Two Bad Guys does this.)

    Examples of Mister X and Mister Y include:

    Comic Books

    Fan Works

    Films -- Live-Action

    Literature

    Live-Action TV

    Music

    • The song "Mister Gallagher and Mister Shean" by Ed Gallagher and Al Shean. Probably the Trope Maker; certainly the exchange "Absolutely, Mr. Gallagher?" -- "Positively, Mr. Shean" became a popular meme.

    Theater

    • In The Golden Apple, shifty stockbrokers Mister Scylla (played by the same actor as Menelaus) and Mister Charybdis (alias Hector) do a pastiche of the Gallagher and Shean number.
    • In 1776, when John Adams and Thomas Jefferson are arguing over who will write the Declaration of Independence they refer to each other as Mr. A and Mr. J.
    • Classic Vaudeville Schtick: e.g. Mr. Bones and Mr. Jones, done by such as... Mr. Gallagher and Mr. Shean.
