I figure it this way: a) We all like to spout off our opinions
  as if they mean something. b) We each act as if we're President
  of Earth making proclamations that everyone should listen to and
  agree with. c) "If only everybody would listen to me, the world
  would be a better place."* is often what people think when they
  state their opinions. d) So... with a new "Earth Flag" that
  everybody's talking about, why not go "ALL THE WAY" and just
  make myself *President of Earth"? Now I can answer, "Who died
  and made YOU President?" :P [and the LAST thing I'd want is to
  be President of anything.* So, if I had to do it, might as well
  be president of everything and keeps spouting off my ridiculous
  opinions as if they mean something just like I would've done
  anyway :P ] Humility through excessive absurdism :P Thank you
  rare avis :) You can have a Seat as head of any Commission you
  like. :P
