A Portrait of the Artist as a Young Man
by James Joyce (excerpt)
The Vances lived in number seven. They had a different father and mother. They were Eileen’s father and mother. When they were grown up he was going to marry Eileen. He hid under the table. His mother said:
—O, Stephen will apologise.
Dante said:
—O, if not, the eagles will come and pull out his eyes.
Pull out his eyes,
Apologise,
Apologise,
Pull out his eyes.
Apologise,
Pull out his eyes,
Pull out his eyes,
Apologies.
