Quoth the Raven, "Nevermore."

And the raven, never flitting, still is sitting, still is sitting
On the pallid bust of Pallas just above my chamber door;
And her eyes have all the seeming of a demon's that is dreaming,
And the lamp-light o'er her streaming throws her shadow on the floor;
And my soul from out that shadow that lies floating on the floor
Shall be lifted - nevermore!
