Famous quotes containing the words pitch and/or surfaces:
“Though I have locked my gate on them
I pity all the young,
I know what devil’s trade they learn
From those they live among,
Their drink, their pitch and toss by day,
Their robbery by night....”
—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)
