Famous quotes containing the words pitch and/or surfaces:
“I dream that I have brought
To such a pitch my thought
That coming time can say,
“He shadowed in a glass
What thing her body was.””
—William Butler Yeats (1865–1939)
“But ice-crunching and loud gum-chewing, together with drumming on tables, and whistling the same tune seventy times in succession, because they indicate an indifference on the part of the perpetrator to the rest of the world in general, are not only registered on the delicate surfaces of the brain but eat little holes in it until it finally collapses or blows up.”
—Robert Benchley (1889–1945)
