"Yeats was an inexhaustible source of delight. I’ve never known anyone so forgetful of little details. Whenever it came time for his lecture in on the campus, he seized his portfolio and marched over only to find after he arrived on the stage that he had brought the wrong lecture or no lecture at all in an empty portfolio. This was constantly happening."
