Ambrose Bierce - Egotist

Megaceph, chosen to serve the State
In the halls of legislative debate,
One day with 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 know how every member stands,
A man who to all things under the sky
Assents by eternally voting 'I.''

Ambrose Bierce
