Famous quotes containing the word oil:
“As artists they’re rot, but as providers they’re oil wells; they gush. Norris said she never wrote a story unless it was fun to do. I understand Ferber whistles at her typewriter. And there was that poor sucker Flaubert rolling around on his floor for three days looking for the right word.”
—Dorothy Parker (1893–1967)
