Famous quotes containing the words dirty and/or data:
“The trouble with writing a book about yourself is that you can’t fool around. If you write about someone else, you can stretch the truth from here to Finland. If you write about yourself the slightest deviation makes you realize instantly that there may be honor among thieves, but you are just a dirty liar.”
—Groucho Marx (1895–1977)
“This city is neither a jungle nor the moon.... In long shot: a cosmic smudge, a conglomerate of bleeding energies. Close up, it is a fairly legible printed circuit, a transistorized labyrinth of beastly tracks, a data bank for asthmatic voice-prints.”
—Susan Sontag (b. 1933)
