Famous quotes containing the word twist:
“I believe in the total depravity of inanimate things ... the elusiveness of soap, the knottiness of strings, the transitory nature of buttons, the inclination of suspenders to twist and of hooks to forsake their lawful eyes, and cleave only unto the hairs of their hapless owner’s head.”
—Katharine Walker (1840–1916)
