Famous quotes containing the word light:
“A favorite of outdoor alcoholics, connoisseurs and Fundamentalists, these pills turn water into wine. In 10 minutes the most fetid swamp scum in the forest can become modest red, elusive and light on first taste, yet playful—one might say a trifle impudent—on the afterbite. Saves pack space by eliminating need for bulky corkscrew, decanter and bottles. Store pills on their sides in a cool dark place.”
—Alfred Gingold, U.S. humorist. Items From Our Catalogue, “Wine Pills,” Avon Books (1982)
“Run to your houses, fall upon your knees,
Pray to the gods to intermit the plague
That needs must light on this ingratitude.”
—William Shakespeare (1564–1616)
“We not only grew up on Be-Bop; Be-Bop raised us. For my generation, Be-Bop came on like a light bulb going flash behind the eyes. For us, it was not only an intellectual movement, but a way of life. We walked, dressed, and rapped Be-Bop.”
—Ishmael Reed (b. 1938)
