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
