EGOTIST, n.
A person of low taste, more interested in himself than in me.
Megaceph, chosen to serve the State In the halls of legislative debate, One day with all his credentials came To the capitol's door and announced his name. The doorkeeper looked, with a comical twist Of the face, at the eminent egotist, And said: "Go away, for we settle here All manner of questions, knotty and queer, And we cannot have, when the speaker demands To be told how every member stands, A man who to all things under the sky Assents by eternally voting 'I'."
--Ambrose Bierce - The Devil's Dictionary
