Famous quotes containing the word iron:
“If you think dope is for kicks and for thrills, you’re out of your mind. There are more kicks to be had in a good case of paralytic polio or by living in an iron lung. If you think you need stuff to play music or sing, you’re crazy. It can fix you so you can’t play nothing or sing nothing.”
—Billie Holiday (1915–1959)
