Famous quotes containing the word paper:
“There’s a long story, my friend. I never did like the idea of sitting on newspapers. I did it once and all the headlines came off on my white pants. On the level, it actually happened. Nobody bought a paper that day. They just followed me around over town and read the news off the seat of my pants.”
—Robert Riskin (1897–1955)
